I am about to pull my hair out! Here’s my situation. My blazer has had some (poorly done) body work by the previous owner, at least one of my doors isn’t the original, I recently found a nice double wall top, and I changed my old body mounts over to a poly kit a couple months ago. I can’t get the new mounts shimmed so that the top and doors are both happy. Everything that I have read here and in my assembly manual says to shim the mounts so that the doors close nicely, but as I remember, these hinges have a little bit of adjustment built in to the mounting holes. My question is if the previous owner mounted the doors with to the old worn out body mounts, wouldn’t I probably have to adjust them now that I have changed things around? If this is the case, I seem to have too many variables! Where do I begin as far as shimming these mounts??? By the way, the hinges don’t really have any sag to them, but the doors seem to be hanging too low at the striker area. However, the vent window area of the doors match fairly well with the windshield frame. What does this mean other than my body is a pretzel?

Re: Body mount shim pain in the @$%!!!
Is the hard top mounted?
Mounting the hard top will set the firewall/B-pillar alignment fairly well. Hinges must be in good shape, if their not, now is the time to rebuild them. Don't worry about the striker plates or latches yet, get the door gaps set first, then adjust the latches and how the door closes from there. |

Re: Body mount shim pain in the @$%!!!
Need more info---front clip on? Torque boxes in place and good? YOu shim to get the body straight where it flexes at the front floor.
The door hinges give you front to back , tilt and forward and back at the A pillar! The in/out at the door mount. The shims will allow for door to quarter and door vent window to windshield frame alignment. If your door to quarter and door to fender seams are kaka, you will need both shimming and hinge to A pillar adjusting. Take your time and do one at a time. Sent you PM with my phone # for some verbal encouragement !!hehehe Huck |

Front clip is on, torque boxes are in place and in good shape, floor pans have some rust but not as bad as some I have seen. Keep in mind I think this thing has had a pretty rough life and I doubt any of the front sheet metal is the orignal. None of the gaps seem right anywhere on the truck. I am hoping to get this straightened out and then move forward. I have been adjusting the main mount under the front floorboard and the next one back which is just behind the front seats. I have been doing things as the assembly manual says but it tells you to use the doors as a reference point. I think the hinges DO need to be adjusted so that tells me they aren’t a good tool to go by. My main problem is where do I start? Should I shim the body mounts so that the top fits? I finally got it where the bed rails and top are touching all the way down the sides. THEN should I adjust the door hinges accordingly? I just feel that there should be a definite pattern of steps to follow but maybe there isn’t. I’m a terrible body man, it requires WAY too much artistic talent! One last thing. I did at one time have the mounts shimmed where the doors closed pretty good. When I put on the top, I bolted it at the windshield and at the very back and this created about 3/8ths of daylight between the tub and the B pillar, this didn't seem right so I continued to adjust shims. Thanks for all your help guys, I really appreciate it!

Re: Body mount shim pain in the @$%!!!
I'm about to go thru alot of the same grief you're feeling Critter. I have to align almost all my panels after pulling the body lift out.
Where did you get this assembly manual? I did a quick google search and found the 67-72 truck assembly manual. Is the K5 covered in the same manual? Last edited by AJs72K5; 04-09-2008 at 07:17 PM. |

The K5 is in the same manual as the trucks. It is very confusing and there is no order to the book, no page numbers, no index nothing! BUT it is very helpful when trying to figure what parts go where, once you find the right page. You are welcome to take a look at mine sometime if you like.

Re: Body mount shim pain in the @$%!!!
Looks like your door is a little too tight at the line between it and the rear quarter. The assembly manual gives you specific measurement recommendations at all seams. I like to get that seam good, then go for the vent window frame to windshield frame seam. Last is the front of door to fender---Your fender adjustment is infinite and easy once the stuff behind it is done. huck

Re: Body mount shim pain in the @$%!!!
I've been helping him out when I can and I can tell you this, it is a pain. Once we get one thing lined up the rest of it sucks and vise versa. I thought I woud bring up another point. The back of the top is very difficult to get lined up as well, like it hangs too much off the back. Critter, maybe you did something else recently to fix that but that's what I remember.

Re: Body mount shim pain in the @$%!!!
I think you should loosen all your body mount bushings and then put your top on. Then use a couple of floor jacks and some 4x4 scrap and jack up the body until the gaps between the body and the top are right and you can bolt the rest of the top to the body. Once you've done that, shim your body mounts properly and tighten them down. Then lower the jacks slowly. That should fix it. Let me know when you're gonna do it and i'll help. Later, Mario.

Re: Body mount shim pain in the @$%!!!
Don't scare them too much. I have a feeling that my blazer has just been so molested that it is worse than most. It's pretty apparent that mine has had some pretty questionable body work done over its life, not to mention sheet metal replacement and poor adjustment. Luckily, the mechanical and electrical are in pretty good shape. If the weather would ever dry up around here I would tear into it again.

Re: Body mount shim pain in the @$%!!!
Dude, if you shim it with the top on and compensate for body mount compression when you lower the jacks, your top will be fine. We'll lower the jacks slowly. Later. Mario

Re: Body mount shim pain in the @$%!!!
I spent most of the day on Friday shimming the body mounts on mine. On the driver's side, I got the a-pillar, b-pillar, and rocker lined nice. The door closes beautifully. However, my gap on the windshield frame is off. It's good at the bottom, but is almost rubbing at the top. Suggestions?

Re: Body mount shim pain in the @$%!!!
Or we throw the tops away and cruise topless forever, seems to make the most sense to me.

Re: Body mount shim pain in the @$%!!!
Listen to Mario---he is pointing you in the right direction. Use his as a reference point. Don't worry about damaging the double wall top--around here we throw perfectly good one's away!! hehehehe Besides you really would be happier with a single wall. It cuts the weight by about 3 lbs! hehehehehe---
Oh yea, one more little tidbit about Blazers---let's just say after you spend a month or two trying to get everything lined up nice---and you get the bug to drive it topless---like some many things in life--topless will over time make things--well---sag a little!!hehehehehehe You will have to put the blazer top bra back on to get things line up close to the "perky" way you had it before!! (:>) |

Re: Body mount shim pain in the @$%!!!
the other thing on door alignment, don't be afraid to hog the holes on your hinges at the A-piller just a bit to give you more adjustment for gaps, It makes it easier, and done easily with a good carbide burr on your die grinder.
On mine it was top on and bolted in place, original shims back into original locations and walla, just a bit of door alignment and good to go. I have a very rust free tub though and a good set of OEM doors. |
