Newbie here to the site and K5 Gm trucks.Great site.I just bought a 91 GMC Burb off of Ebay for $4600.I think I got a good deal.I've spent a ton getting everything that was needed done(fluids, EGR,Interm. wipers and lots of new Int. parts from Chevy duty).6 '' superlift sitting in the Garage that I'll put on after the roof is repainted.West Tex. truck that had a rack on the roof.Well the rack was removed but they left me plenty of holes to get filled. Did the 91' GMC v1500 have a HD susp. option?Mine has Fact. dual front shock mounts and the larger Dia. tie rod(1 1/4'' I think)that also gives me the 4.10 rear end also.Anyone know anything about this?
