I am a first time 4x4'r (trucks that is, I am an ATV'r, in his 40's, been hot rodding most of my life..., but this is my first 4x4) OK, you guys were right, I am hooked, and my wallet it emptying fast! Here is the truck the way I bought it: It had been sitting for a year or so, and only driven very rarely for the 5 years before that, prior to that, I have no information on it at all... I paid $1250 for it, and drove it away. First modification was a set of duals, with Flowmaster 30 series. The headers were almost new, so are in good shape. Second, I got a good deal on a set of 36 TSL's that had been tastefully trimmed: Next, I tested, tuned, tweaked and painted it all black primer to get it at least looking presentable... I took stock of what I have: 1978 K10 (frame and bed and running gear) 1980 GMC Body 3-4 inch body lift 4 inch suspension, springs in front, springs and block in rear SBC 350 seems to have life left, runs out good Weiand intake (not sure of model yet) Edlebrock carb (again, not sure of cfm) Newer headers, not coated, but seem to be a good set New exhaust with Flowmasters Rebuilt TH350 (I know for a fact, have reciept) NP203 with a part-time kit, (don't know what kit) seems tight, no noises, and shifts fine, no slop) Dana 44 in front, have not confirmed, but RPM vs Speed (radar checked) indicated 3.73's engine pulls them fine for now 12 bolt corp in rear. I do know know for sure, but I think both diffs are open, it is possible that there is LS in rear, but not for sure... 36 inch TSL's in nearly new condition solid frame, no cracks by steering. front springs are a little saggy..... rears are fine Some body rot, but nothing that needs fixing for now Exhaust leaks by headers AND collectors, driving me NUTZ Suspension, balljoints and such, seem tight enough for now, put a new steering stabilizer on it, it was missing... OK, it's running fine, and everything works... I have about another grand I can put in this truck... question? WHAT? I have thought about a limited slip for the front, and a locker for the rear.. I have thought about dana 60's with 4.10's, but I already have these tires... and don't really want to change. I know the weak points are my axles, but I don't really want to buy new tires and rims.. can I beef up these stockers?? and add a locker to the rear? I am not going to try to crawl this truck, I think I want it set up for mud and trails.. Can I beef up the axles and U-joints and everything enought to put air lockers front and rear? or is that just a waste of money. I really think I want to spend the grand on locking this baby down, even if it means finding 8 lug 15 inch wheels, grinding calipers and such, and using dana 60's... but I don't think a grand will buy all that.. Suggestions? damn, I just looked, this is a LONG post!!! sorry!!!
