hey Tim! Question for you. I ordered a set of upper control arm bolts for the polara. They look very close if not the same to that of the A body ones. However, the ones on my 64 polara are completely different than what came in. I'll get some pics this evening. But i don't see how these are used. On the polara, there is a bolted on bar/rod in the frame, the bar/rod does thru the upper control arm bushings and then are held in with nuts. Part number search verified that the ones I ordered are for a 62-72 B Body.
