Good day. My wife recently bought me a 2002 S10 Crew Cab, she is awesome. I do have some questions about it. The truck doesn't have any stickers/decals on it, so I was wondering how do I find out the specifics are for the model? I read that the ZR5 comes with rails on the bed & roof (I don't have those), & alloy rims (I do have those). It is power everything inside & I found out that I have the older style stereo (1.5 DIN). Thanks for any help you can provide.
