To start off I had to prepare the truck for the PC. First I did minor mechanical maintenance to ensure it will run another 145k miles.
That done I started on some cosmetic changes I wanted. I changed the sliding back window to a single piece of glass. Then I removed the 60/40 bench and added buckets from a newer Tahoe. (Ignore the torn upholstery, I plan to recover them.) I stripped down the dash too. Finally, I added a Python alarm and shaved the door handles.
