OK, well, im 16 and I just got my permit and Im getting my license some time around February. Im driving my dad’s old 1983 GMC S-15 High Sierra Pickup truck that he’s had since before I was born, and I want to fix it up and make it look like this S-15: http://www.cardomain.com/ride/3012400 .

so far we are going to put a 3 inch body lift on it and straight-pipe it but we need to know what accessories these are on this truck, I pointed them out in this picture and numbered them so they could be answered accordingly. also whats the tire-size on that?

for #1, I meen whats the thing over the windshield and windows

Ok you basically have the whole lund catalog there.

1 would be sun/moon visor and rain /wind deflectors
2 would be a cowl induction style hood
3 would be a bug/wind deflector
4 would be taillight covers
Tire size is between 31-33 inch overall diameter and 9.5-11.5 wide

Heres a few links

I recommend you find a body lift that has bumper relocation brackets. Notice how far the rear bumper in your pics is from the body. That is because it has a body lift and did not relocate the bumper along with the body. Thin 33s or 31s would look good on that truck. Thicker tires will scream 80s.
