Hey,
My friend working on the 72 th400 to m-20 swap just told me the crossmember for the auto is different then the standard. I thought they were the same? Anyone have one?

Oh ya the difference in the cross members is one is removable and one is not. The auto cross member is the removable one.

I'm pretty sure that the rubber mount is also different.

we just finished ours and you will also have to weld on the two little brackets that mount to the trans mount bracket you are adding.

could you post a photo for me or email it to me. where did you get the 2 little brackets at. I have the th350/m20 bracket coming already.

I didn't have to weld anything mine was a complete bolt in??

there are to small brackets welded to the standard 4 speed cross member. the auto cross member doesn't have them. I made mine out of angle iron. zips selsl them but they had no stock on them. you can mount the trans bracket with out them but I didn't.
