A: That would be tough to find except maybe on EvilBay. Unless you are going for an overdrive trans, Jeep TH400s ('74 up for AMC only cases) are available lots of places. If someone needs the other ring, I have one of those for sale, along with a used 360 flexplate and the crank adapter/spacer) From: svtamc@xxxxxxxxxxxxx Subject: WANTED Trans adaptor To: mail@xxxxxxxxxxxx Message-ID: <ADVANCES62ednHM3SOl0000006f@xxxxxxxxxxxxxxxxxxxxxxx> 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. Thanks, Jeff G. Tampa 74AMX 79AMX
