Cummins Swap 1968 Suburban - wish list

[Reno]

I've followed posts on the site so i thought I would reach out for advice.

I'm gathering parts for a Suburban with Cummins build

Heres what I have so far

1972 Suburban K10 rolling frame
1968 Suburban rust free body
1992 D250 Cummins Pickup with auto
Rob Bonney Frame box kit & motor mounts

With Black Friday here and vendors offering deals what would you buy?

I'm older and don't want too much lift. This will be a daily driver - I live in Colorado.

I believe the Front & Rear differentials (Dana 60 & 70) from my donor truck will work. Strong running 5.9 but it has the VE Rotary pump so looking for the required parts to upgrade to P Pump. The auto trans is slipping as it was a snow plow truck.

thanks in advance.
