Sub-frame connectors

a buddy of mine builds older mopars to race circle track as a hobby, his dad used to race ARCA series in the late 60s and early 70s, he has a lot of information on this subject as his dad used to be in touch with Chryslers former chassis engineer on mopars stock car program. A man by the name of WWWLarry Rathgeb.

i asked him about the subframe connectors for my cuda. he said level the car body shell on 4 jackstands. i asked him how do i know its level the concrete floor could be slightly off. he said you shim the jackstands where they meet the body with sheetmetal shims as necessary to make it level. said to use a couple spirit levels. you know the bubble levels carpenters use.

build andand fit your conectors first, then when your ready to install them you will need to jack and level the car before welding them in.

set a spirit level on each rocker panel in each door opening where your door sill plates screw down, same location both sides. set one across the flat upper shock mounting panel in the trunk, and one across the radiator upper support inner flange, this is where its flattest here. if radiator is in car just loosen the bolts and lay it back.

then its jack and shim until all 4 levels are centered. then fit your subframe connectors in, clamp, and tack weld in a few spots. recheck your levels to make sure they are still level, then zap it all together. these cars arent built perfect so dont expect the bubble levels to all be dead on center but they should be really close.

as another poster said you can align body panels to suit when it goes back together. these cars werent robot welded and therefore arent perfect. but are close enough to work. from his experience welding the connectors into an empty leveled shell is preferred over preloading the body.

just my .02 and some ideas
