4spd to T-350 swap info wanted 67 c10

[CoolRide]

I'm comencing to start thinking of getting ready to swap out my 4 speed in my 67 2wd c10 pu.
For a turbo 350. And while I have swapped out power glides for 350s before it has been years ago, and a little different procedure I'm sure.

Pretty sure I can figure out how to get my 4 speed out in mostly one peice (depending on how much it pisses me off) but, what do I need to be thinking of doing to get my 1976 short shaft T 350 in its place?

Once the 4 spd is out I will pull flywheel and put on flexplate that came with t 350?

Then bolt on torq converter to flex plate ?

Sorry, as I said its been a long time...

I just read in another forum that the crossmember/ trans support are possably located in two different places for the 4 spd and auto trans?

I have been busy upgrading the engine (read, making it drivable after sitting in the back of a shop since 1980) and have not gotten under it to look yet, this swap is just something I am trying to get a little info on now, so when I'm ready in a month or whatever, it will go smoothly .......Ya right lol.

Thanks for any thoughts, ideas, tips.
