We got Steve's brew truck finished and delivered today. 57 Chevy long bed step side, started as a 1 ton, now a lowered real nice driving hot rod beer hauler for his little brew company, 5.3 LS swap. 4L60E trans with 2500 stall, 8.8 mustang housing with 3.73 gears. We also replace the bed floor with new oak bed stained to match the body color and new stainless straps and rear mount fuel tank with a side mount bed fill and the interior was updated a little as well with Dakota digital gauges and a newer Colorad split bench, and a retro sterio with a sub and Amp installed by Jared.

Enjoy Steve
