67 292/M20 4spd to 292/th350

[67C10SWB]

I did a search and found a lot of data for tranny swaps and I may have missed it but I want to know the following. I would like to swap out the M20 in my 67 c10 to a th350 that is currently in a 78 1/2 ton. So the finished setup would be the 67 292 with the th350. I understand the cross members and drive shaft mod but what about the two, will they bolt up? Can anyone give me the scoop on this or forward me the link with the answers. I appreciate it!
