1. Last month we reported that the 4L85E transmission necessitated either some fabrication on the stock crossmember, of the purchase of one ready to go. We opted to pick up this ready-to-go crossmember from G Force. As you can see, this is one hefty piece of steel. it is designed to fit the '70 Chevelle, but with the new longer transmission. The exhaust clearance bumps are a welcomed upgrade over the original piece.
