Re: 1972 Build thread.
Body is officially on the frame.
I have a couple of small issues. (#1) The body is touching the top of the transfer case. Just a smidge.looks like an easy fix, but if I drop the t-case an 1" it may create an issue with the tall valve covers kissing the firewall... (#2) The soft ride springs in the rear have my rear axle forward at least 2-1/2"... not OK, this will get addressed as soon as I educate myself on the issue. I have been seeing this on lifted Blazers for a while. (#3) passenger side header does not fit. It is swept back to far, the flange is almost up against the body flange at the bottom of the firewall. They were cheap headers from a local mom and pop shop here in town. Everything else seems good for the moment. I'll elaborate with some pics in a little while. Thank you Classic Heartbeat... the body mounts were top notch.

Re: 1972 Build thread.
Ok...
Doing some reading... on this forum for the most part. A big thank you to everyone that pitches their experience and information into this community. Here are my issues. I switched from a Rockwell transfer case to a np205 transfer case, the 205 should have been original equipment for this model. Therefore it should fit, unfortunately mine does not. I am learning that there was a 3/4 ton crossmember, and a 1/2 ton crossmember, the 3/4 ton being a taller crossmember? The 3/4 ton frame being taller allowed for this extra height... I do not know how to confirm this to be true. Regardless, this appears to be my issue. Any feedback on this from anyone? The fix? I get a 1/2" or 1" spacer kit... Problems that the spacer kit will create? I may create a front driveline/deep th350 pan issue... I may create the tall valve cover/firewall issue... although, I think I already have the valve cover issue. Grrr. Plan?... Change the tranny pan out to something less awesome. Burning $$$... Put a dent in my firewall with the double hammer method since my valve train will not low me to use standard valve covers. Pit in stomach... Any other ideas on this one? One other item, my mounting location on my frame on the passenger side forward mount appears to be bent down about 3/4 of an inch... on the outside , not the inside of the ear... eye twitching. Although I'm not super concerned about this since the doors fit and opened/closed really well before I took them apart... So I tell myself.

Re: 1972 Build thread.
Can you post photos when possible of how the tcase is mounted at the frame rail and at the crossmember? The crossmember for the tcase should be same 3/4 or 1/2 t. Is it SBC bolted to th350 bolted to the NP205 with OE adapter to the tranny?
Brad had what may have been a similar issue albeit with a 69 cab. Is there a chance the case for NP205s was changed at some point with a later style less accommodating for these trucks? Just a thought as neither his nor yours were original to the vehicles. Maybe ask Brad to weigh in. Here’s his relevant post on the matter: http://67-72chevytrucks.com/vboard/s...&postcount=152

I read that thread, same issue. I will follow up with him, I thought he had a low hump cab? Can't remember now, I will re-read that thread.. Yes sir, I have a sbc/th350 - but I am bolted to the transfer case with an advanced adapters piece as a replacement to the original adapter. It does not appear to be clocking the transfer case different than stock. Although it could be a taller piece due to it being made from aluminum they may need more material for the required strength.... hmmmm... I read up on 205's after reading your post. They changed in 1985, last production year being 1991. Mine is out of a 78 something Cheverolet with a 4spd. Here is a picture or two. Let me know your thoughts, I hope I missed something that you are about to catch. Thank you again for taking the time to help. .

Re: 1972 Build thread.
Are the brackets present and in original factory location to affix the tcase to the frame rail? Not just xmember.

Re: 1972 Build thread.
Yes sir, everything lines up as it should. I'm waiting for my transfer case side support to be finished at the powder coater, I checked it before dropping it off and it lined up with the frame holes as well. I feel good about it being in the correct location. Head scratcher.

Re: 1972 Build thread.
The advanced adapters piece is an exact copy of the original, not of the earlier model, but of the later model. I need to look into this, and if there are differences between early adapters and later adapters. Long sigh.

Re: 1972 Build thread.
I can take measurements if you like, as I have the same basic setup, my fingers just fit above my t/c
8quart oil pan and a deep trans pan I was thinking tc mounts, but you have the same as me

You can use something like this to move the axle back in the wheel well. https://www.wfoconcepts.com/pr/Leaf-...n-Plates/20071 There's similar parts available just find the one you want. Another option is to remove your rear axle, cut off the stock perches and weld on these: https://www.wfoconcepts.com/pr/2-5-L...rch/16871/3373 I went with option two to center my axle up in the wheel well. For your headers I'd recommend Sanderson headers. I used these and they fit and look amazing. Happy to post a pic if you want. https://www.sandersonheaders.com/san...ategory_id=551 |

I was actually looking at the old school Sanderson manifolds, I didn't look at the headers yet. Thank you for the link on those as well, it is good to know that they fit. I'm going to wait and see how this all meshes together once I adjust the transfer case so the body can be fully mounted. Maybe The header will fit after everything is in place... I doubt ut will, but here is for wishful thinking. I love your Blazer's stance, what is your lift/tire set up? It looks amazing. Thank you again for taking the time to respond.

Re: 1972 Build thread.
The one thing I can't do, my mounts are messed up right now, but if I can assist in any other way just ask

Re: 1972 Build thread.
It might be a good solution, raise the body up to what ever you need. I have a lathe and bridgeport, if you need me to build the spacers

From what I can see, all of my body mounts are on flat against the body, but not tight. This is except for my passenger side front. It seems to have a 1/2 or 3/4" drop at the outside, looks bent... ![]() If it was easy, everyone would be doing it? I guess... ![]() I hope you all have a safe and happy Thanksgiving!!

Re: 1972 Build thread.
It really isn't a bother, I'm a retired machinist always looking for something to do, so
after i tinker on the Jimmy. I would guess a couple of minutes on the bandsaw, then the lathe, project should be done in short order. Round stock should be available from McMaster's the next day. I just figured out your avatar, think it means sunscreen (SPF), and if it does, then it would be helping a fellow fisherman out. Just don't ask for a fly pattern that's working on the river lol Ps, I fish for 35 lbs salmon, and 20lb steelhead, never saw a sturgeon where I fish lol, only have one steelhead mounted in 40 years of fishing, all catch and release That body mount does look to be bent, I have one of those as well, if you want to drill rivets, PITA Anyway, wishing you and your family have a safe and happy Thanksgiving, keep in touch

I was sick as a dog. Ha! Yes sir, frame/body mount... total PITA, I had to use a jack with a 2x4 to try and get it straightened. I got it back about a 1/2" out of the 3/4" I was dealing with... it is a really good way to try and get hurt as well, let's say that. So far it is close enough and I may pay for that statement when aligning fenders. Thank you so much for the offer to help, it is truly appreciated!! I hope you have a great week!!!

Re: 1972 Build thread.
Do you have adequate t-case clearance now?

Re: 1972 Build thread.
Negative, but thank you for checking in on me.
![]() I am better than where I started. Once I did the hillbilly 2x4 method, I had also noticed that the sides of the body mount on the frame were bowed out. I used a dead blow hammer to get them tucked back in straight. I performed this high IQ process a couple of times and appeared to get the mount moved back up about a 1/2". The body puck fits with less than a 1/4" gap, I can move it around easily, but not pull it out due to the lip catching on the frame mounting hole. There are a couple of knowledgeable 67-72 guys here where I live that have run into this transfer case issue before. No one had a reason why.. One of them shimmed the body up with large washers, and one dropped the transfer case down a smidge. I'd rather shim the transfer case down a touch than lift the body any higher. There was also the suggestion of moving the whole moter, tranny and t-case forward to the c10 position. I'll pass on that one. I have a fair amount of items to attack at the moment. I will get the wiring under the dash complete before I mount the doors... once the doors are mounted and I start putting the fenders on, I'll figure out what needs to be done with this body mount. I assume that it will mess with door alignment if I crank it down how it is.

Re: 1972 Build thread.
Check. Any idea what occurred to bend the mount? Are the other mounts in good shape? I’m still puzzled by the lack of TC clearance and wonder if a settling tub because of sagging mounts could be the cause.
