SM465 Specs for 4x4 Application

[cleszkie]

I'm looking for an SM465 four speed manual tranny to replave my TH350 auto in front of my NP205 transfer case. There are a few variants out there and I want to make sure I get the right one. Am I looking for the long or short output shaft version to work with the adapter I need between the SM465 and NP205. This is for a 72 K5 Blazer, so I am talking about the adapter that was used for this era truck (the length of the SM465 + adapter = length of TH350). Thanks.
