Greetings from a fellow Richmond-er. (I'm in the Stratford Hills neighborhood.)
I have an `89 SWB/SC. Originally a V6 Cheyenne, but undergoing some ride-height and powertrain modifications.
I'm certainly not an expert on these trucks, but I've completely gutted my truck; notched the frame; replaced the front suspension; (mostly) figured out how to install a hydroboost brake booster (for engine clearance); and gotten very familiar with the C.A.P. truck junkyard.
Look forward to seeing your progress with the Burb!
