Putting together a 1964 K20+ 1964 c10 body + 1977 K20/C6P

I'm mounting a 350 engine to 1964 K20 Frame
the 77 K20 had 350 transmission with 203 transfer.

How can I mount a 700r4 4sp/OD to 203 Transfer?
need to find output shaft and spacer

The 350 CID was rebuilt with Vortec heads Elderbroc performer intake and Elderbroc performer Cam.

Now I would like to change the Transmission to an OverDrive from my 1992 S10 4wd 700r4 transmission .

We mounted the 77 K20 Axles and added Warn hubs.

May have another option of getting a 700r4 and transfer already mated but don't know the price yet, if it is to expensive I'll try using what I have.

Help and advice is always appreciated. Does anyone see any troubles that I'm facing.
