Here's my 78 K-10, this picture was taken in about 1984 in the White Mountains of Az. The truck had 33 1250 15's on Enkei 15x8 model 32's with Anodized centers. The wheels were done as a custom order for Giant Off Road Centers, they did a 100 blue and 100 red. It also had a Rough Country triple shock hoop with B Mark 5 shocks.
If you look close, you can see the Penthouse Racing sticker on the rear window which really pulled the chicks! I got it at a Formula 1 race in Canada.
