Monza, your truck is awesome.

I had the little brother to yours many years ago. It was a '63 shortbox Fleetside. Mine came with a very tired 6 cylinder 3 speed that I swapped out with a 283 2 barrel from a '67 Chevelle and a 4 speed out of a 65 chevy 1/2 ton. Mine was also white and the interior looked the same as yours.
Welcome to the Stovebolt.
