Leftover parts build?

[nuke1]

i have a ton of left over parts laying around, a 1998 4x4 frame and diesel runing gear with 4.56 gears and lockers and 15x10 centerline hellcats on 35" rubber, a complete 72 body that will be the truck of choice and as for the drivetrain a 00 4.8 liter and auto tranny with transfer case and all the wiring and everything. Also a turbo off of a 6 cylinder perkins diesel.

Now here is my question do you think that i could somehow get the interior from the 00 chevy into the 72, how much modification would it take? Will i have to stretch the cab? use the firewall.... i am really considering this now

thanks James
