Ridetech stage 2 air ride question

[bret]

I ended up using the little screw jack and a hammer. It fits now, albeit tight, it fits. Just have to drill out the hole a bit where the top of the air shock goes through (the little plastic piece won't slide through to connect to the other plastic piece) and it'll be good to go. Thanks again for the help!

While you should NOT have to go through such gyrations to get our control arms installed, you apparently have a stacking of tolerances that have contributed to the situation. While your subframe is "new", I believe it is a reproduction of the OEM unit. The reproduction manufacturer had to model his product off of an original and "unmolested" subframe. This is harder than it sounds. OEM chassis and body components were NOT computer modeled until well into the 80's, therefore there are no digital drawings available. Hand drawn prints were used to build jigs, prototype units, and subsequent production parts. Even if the reproduction subframe manufacturer used a truly unmolested component to create their product, the oem tolerances could have been to the high side or low side [or a combination of both] and still been "within spec". Add to that the inevitable manufacturing tolerances that exist to this day [although much smaller than 50 years ago] ...AND the inevitable manufacturing tolerances of mating product form other manufacturers [ours in this case] and it is not hard to imagine coming up a few thousandths of an inch from a perfect fit.
I explain this not to deflect responsibility for proper fitment away from us or the subframe manufacturer but simply to explain to the rest of the forum how these situations come to be. Fortunately todays design and manufacturing processes have minimized these situations for newer cars...those parts are relatively easy to prototype and build for proper fitment.
Isn't hotrodding wonderful!
