Does anybody know for SURE if the lower control arms on the front of a 3rd gen A body(68-72) interchange with a first gen F body(67-69). I didn't think so but saw an ad on ebay today indicating they did interchange. I know uppers are different and steering linkage is diff but I'm not sure about the lower arms.

Hmmm...

I've never heard of this Dennis.

The only thing I've heard of lower control arms swaps on first gen camaros and novas is the "metric" lower control arm swap. Don't know the details or I would share :(
