Re: Frame Sag
yep, they are the polyurethane red mounts, cant remember the name of them, but they also make the stops and bushings for leaf springs etc., yep that was the first thing i checked to make sure they were the right height etc., any ideas to stiffen up the frame/body?

Re: Frame Sag
If you used the new mounts at the time of your build shimming is the way to go. I wld suggest loosen your body mounts in the area that you are trying to fix and start jacking up the body from the middle of the truck with a 4x4 spanning th rocker boxes til your lines are where you like them and then fill the gaps on the body mounts with shims and you're good to go. Hope that helps. Mario

Re: Frame Sag
If you're going to add more shims, or adjust some, I'd recommend loosening all the body mounts on the tub. Otherwise you can cause some binding. It's a very tedious process.

Everything your describing suggests your body mounts are not correctly adjusted, either not torqued enough, not shimmed enough or could even be torqued to much or shimmed to much. Also, the torsion boxes ARE what's meant to keep the tub rigid in the door area, that's exactly what their there for, pull the rear cover off and check em out. How are the lower 'A' pillars looking? Is there any noticeable rust on the tub? Keep in mind that these frames are designed to flex, have you compared it to another one to see if there's any differences? Pics of a "good looking" lower 'A' pillar for ya. #1 - looks pretty solid #2 - ...guess not after all. #3 - Here's the internal support system, it isn't your door openings sagging, it's your firewall moving/flexing here. |

Re: Frame Sag
I have this same problem with my '72, but I haven't taken it apart yet to investigate the issue. I've read several threads about this issue, and everyone always says shims will fix it. They are probably right, but I don't know for sure. This link to a similar thread might help.

Re: Frame Sag
If they are aftermarket this could be some of the issue, I had this problem.

Re: Frame Sag
Repops aren't made. You'll have to start searching for used ones. If you become a subscribing member, you can post a "wanted-to-buy."
