Need advice 63 C-10 4x4 build

[diablo03]

I would like to start collecting parts for this build so I can complete it this summer, but I want to get a good plan together before I start randomly buying parts.

I'm trying to do a budget build here (don't have unlimited funds for this project) but I am looking at my options.

Currently the truck is a 2wd, lwb, c-10 with 4 speed, 292.

I would like to keep the 292, but make it 4wd. if a complete chassis swap would be easier for the 4wd I would be willing to do that.

I would like to have 33" or 35" tires and an auto tranny.

I am willing to buy an older silverado to use as a donor truck or a chassis base.

any years easier than others? Issues with retrofitting the newer auto column to the older cab?

I'm not afraid to cut things and rebuild things, so please come forth with the suggestions.

Thanks in advance.
