pictures of buffalo enterprises tranny adapter

I’ve got a 1948 GMC truck with 216 ci engine. I want to install an auto transmission TH350. I already found the kit with adapter plate + flex plate 168 tooth + starter.
Do I need to modify the Driveshaft to connect the TH350 to my original Rear End or can I buy another that I can fit directly.
I saw some people on the forum talking about Rear End from 1982 S10 4x4. If I just buy this Drive Shaft is it gone fit directly on the Th350 and the original Rear End Axle of my 1948 GMC truck?

 

I found the adapter plate kit for 216 ci Chevy engine to TH350 auto transmission on this web site:
