" From: svtamc@xxxxxxxxxxxxx " " I am looking for a used transmission adaptor that will allow a GM tranny to mate to an AMC block. I need the aftermarket one. NOT the factory one. The factory adaptor that came with the FSJ's in the 70's only works for a BPO(Buick/Pontiac/Olds)tranny. the factory ones only adapt to a buick 'nailhead' 425 th400. i've seen them even on buick 350-engined jeeps. you're looking for something like advance adapters' ring, which iirc has both chevy and b-o-p patterns in the tranny side. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
