For trans If you have a 200-4r the 350 will bolt in the same place and use same crossmember...if it is 200C(non-overdrive) trans then you will need a new trans crossmember.

Here are sbc motor mount position

I don't know what trans I have its small and says metric on it its a 3 speed no overdrive. And what crossmember do I need to get for the th350 and how much will it cost......now I called jegs guy said that the crossmember for 200c will work for th350 I just need to get th350 mounts....any input......all th350 g body crossmembers in jegs say at bottom will not fit any supreme why is that???.....and is the79 cutlass supreme a G body or an A body..........

So I'm at the point were I have to take the frame mounts off....but the way there on there you need to hold the nut underneath to loosen the bolt.....but there's no holes or space to get a wrench in there and hold the nut.....so I think ill use a die grinder and cut da bolts out......its on a 79 cutlass supreme
