I think I'm enjoying your shop and build just as much if not more than you are!

Thank you sir!

[MMcMasters]

We had too much going on today so I only got an hour in the shop today. I got the steering notches cut and tacked in. Then I mocked up the rack to make sure everything was right. Hopefully I will have some time tomorrow to get them welded up for good.





I guess a little work is better then nothing at all.

following, my truck is the oisite of lowered, its sitting on 8 inches of lift, on a 74 k20 frame.

MM, great looking truck you are starting with! And yeah, I am really partial to olive green. I like your build strategy to finish the chassis before taking the truck apart. Looks like fun and I will be tagging along. Nice looking shop too!

[STOCKISH]

Awesoe man! Cant wait to see more!

[mooseknuckles]

nice work! looking forward to more.

Thanks guys

I got the steering notches welded up yesterday but not much more. My shop floor was pretty nasty from all of the dust from the cut off wheel so I figured yesterday was a good time to get that cleaned up and re organize a little. The parts table is dwindling down so progress is being made Next up is getting the engine/trans mocked up to verify pinion angle.

[MMcMasters]

I need some help/advise please


I'm pretty frustrated right now. I received my air bags from back order on Friday. I have a 3 day weekend and was really hoping to finish my mock up but that doesn't seem like its going to happen.

I'm not sure if I received the wrong front bags, or my front lower arms are drilled wrong or I'm an F'en idiot. Here is the problem I'm having.

The top mounting holes of the front bag line up perfectly with the top bracket and the hole for the fitting lines up perfect as well. The bottom mount holes on the front bag are no where near lining up.

Here is a picture of the bottom of the bag and the lower control arm mounting holes.


Measurements for the holes in the bag and the lower control arm




And here are pictures of the upper mount and the holes in the top of the bag. They line up great.





My receipt just says the front uses a dominator bag. These don't have any part number and came in a plain white box. The only markings are "Airlift"



I'm sending Porterbuilt an email too but with the holiday on Monday, I won't hear from them until Tuesday sometime. I'm really hoping to tap into the expertise on here.

Thanks in advance!

Ok, someone way more knowledgable on bags will reply I am sure. Is only one bolt needed (middle one) for holding the lower bag mount in place? And could you go that route for this week end to do be able to complete the mock up?

[MMcMasters]

This is what you get when you try to work while your tired. I swear I read through the instructions on PB website twice and didn't see that I'm supposed to use the center hole only.

I just re-read it and it's right there. I did say In my post that it could be nothing is wrong and I'm just an F'en idiot and now it's been proven (yet again)

I'll get back on it in the morning

We all have those "Doh" moments...I've had so many over years wife and I are both amazed when something goes smooth.

Hahaha, I'm just a moron

the arms were designed for a 6" airbag which has closer bolt holes your running the 7" bags which I highly recommend over the 6" it will be a much better ride. anyway you can re-drill/slot the lower arms or just run the center bolt Ive done that with no issues on several builds

just seen the post with where it says to use the center hole only.

Also just a FYI if your looking for an even better ride and airbag I suggest the Slam specialties SS 7 bag they wont expand when you fill them up so no worries of ever rubbing and are built with an internal bump stop.

Thank you very much for the information, I will check them out!

I really like the color of that truck. I want to swap an LS into mine someday.

I haven't posted anything for a while but I have been getting some work done. I officially have a roller now. I "borrowed" the Coy's we were going to use on my son's truck for the time being. I really want Billet Specialties but after Keith (Bennett68C10) had all of his issues, I am going to wait until I know the problem with the hoops has been fixed.

The rears are 20x10 5.5bs 295/40/20 and the fronts are 20x8.5 5.25bs 255/40/20. Here is what it looks like right now:

[MMcMasters]

My plan today is to get the rear/lower bag mounts tacked on the rear end housing. I have a few questions first and I am hoping for some advice from those who have done this.

I made 5" blocks and I have the flat part of the frame sitting on these to establish my desired ride height.



(1) When I square up and center the rear end, do I want the center of the axle tube centered in the notch at my 5" ride height or when it's fully aired out?

(2) At ride height does the pan hard bar need to be completely flat? In this pic, it is in the center holes on both sides so I have a ton of adjustment.
I also plan to mock up the engine and my empty transmission housing in the chassis to check driveline angles before I tack the lower bag mounts on. I'm hoping it's a productive day.

Thanks for any advice

[MMcMasters]

It still amazes me when I plan to knock a project out "real quick" and 8 hours later I'm still not done. But I do have more questions or am requesting more advice.

I got the rear end squared up, pan hard bar leveled out and I got the engine and transmission in the chassis. I also started building brake lines and got a lot done on them.

I need some suggestions on a vendor who is a familiar with the PB extreme drop and can build me a 2 piece driveshaft and supply the proper carrier bearing and support.

Also, does anyone make a carrier spacer for the new PB boxed trailing arm crossmember? I have an AZ Pro spacer but I didn't know when I ordered it that it's for older trailing arm crossmember and won't work with the new one.

It's really starting to look like I have been working.

[shores6]

As of right now, I don't think anyone makes a spacer for the boxed version. The carrier bearing they use is a 2500HD truck. You can get them at inland empire. As far as the driveline goes, any driveline shop will be able to make a two piece drive line for you and more than likely supply the carrier bearing and make a spacer. Be sure to measure your driveline at ride height, full dump, and full lift to make sure they don't build it too short. You'll be measuring from transmission yoke to center of carrier bearing holes and center of carrier bearing holes to flat surface on the rear differential yoke.

This is gonna be a cool build

[Bennett68C10]

Guess I must have been sleeping cause I missed your new build thread Mike I've been following along on IG, the frame looks great, your moving along pretty quickly.
