Questions about 69 k10 I am looking at

[Growdon]

I went and looked at a 69 long bed 1/2 ton 4X4 today. The body was in fair to good condition, but it does have rust in the normal places (rockers etc.). What I like about the truck is that it is all original (except for an HEI distributor. It has the original radio etc.

It has a 350, 4 speed and the rockwell transfer case. I really wanted an NP205(had one in my Blazer and loved it).

I am going to try to look at the transmission and confirm whether it is an SM420 or SM 465. Did they put the Rockwell behind the SM465?

How hard is it to adapt an NP205 to the SM420 or SM465?

The rig also has drum brakes.

I am going to purchase a 72 GMC K20 for parts that has a 350, TH350, NP205,DANA 44, and DANA 60. Will the NP205 from the auto bolt up to thje SM465 or SM420?

How hard would it be to swap the power brake equipment from the 72 to the 69?

Sorry about the longwinded post, but I just don't want to make an uninformed decision.

I am going to go look at the truck again and I will post further information. Maybe even pictures.
