Hello all. I just picked up my 1991 K1500 single cab. Currently has 186K miles but seems to run and shift well. I've always wanted one of these and finally got one that seems to be a good base to start a restore. After breaking down the RPO codes, It is a Z71 and G80, so it has the off-road package and locking rear diff. It also has the Sports appearance package which from what I can tell is just black grill and some stickers. Anyways, lot's to do in this truck and hope to learn a lot from this site.

One of the biggest issue I'm currently facing on it is that it is missing the emissions stuff (smog pump, egr, etc). Not that I want it but I'd like to pass CA emissions. Looks like I would have to source a parts truck.
