new here and have a quick question

so after working all winter of my freshman year in highschool i have became the proud owner of a 1981 silverado. i was wondering how i can tell if it is a fleetside or not so that i dont order the wrong parts for it

 

fleetside smooth sides on bed,no steps

 

ummm more questions

i was looking at the digital guage set in the catalog. is that just a change the computer and go type thing or is it a lot or electrical work.and how do i know if my truck came with a headliner or not

 

I`m sure if you look hard enough at the roof of your cab, you will know if you had a headliner . And to go from stock to digital gauges, you use the stock wires, plus the kit you order will have more wiring, fun fun
