Just wanted to thank everyone that helped me with picking the right stuff. Except the u-joint /forums/images/graemlins/grin.gif the 1330 is for u-joints with internal lock rings and the 1310 is for u-joints with external lock rings don't think it has much to do with being 10 or 12 bolt. Its too bad because I got a smoking deal on a 1330 to 1350 conversion spicer joint then noticed it was too long and he didn't have the 1310 to 1350 so I had to go to a parts store and pick up a precision joint for $40. Any way to recap so costs so far, 14bolt gov-lock 4.10-$150 7 8 bolt 15x8 w/3.75 bs-$100 U-joint-$40 Synethic diff fluid 75w90,Silicone, brake clean, brake fluid, Grade 8 bolts, etc-free /forums/images/graemlins/thumb.gif (sometimes I love work) 2 Tires mounted and balanced-$40 (did I ever yell at the tire guy for that, f'in rip off). Spring pins-$2 U-bolts w/washers & nuts-$40 So-far $372 (candian prices, probably $250 usd) Only a few problems, went i was ready to let the 10 bolt down it was siezed in the springs at the center pin so I had to take the pin out and the springs spread apart, that was a hassle but gave me an opportunity to flip my overloads /forums/images/graemlins/thumb.gif also I spent so much time trying to get my brake lines of my 10 bolt to stick on the 14bolt and rounded them of with a line wrench so I had to use visegrips finally go it all together and went to bleed the brakes and the bleed screws broke off. I think I'm just going to sell my old 10bolt and buy a rear disc kit. Some of the parts I had to pay for made the install a little more expensive like the stupid tire shop, the u-joint and the u-bolts. Went good took about 3 hrs of actually working on the truck and about 8 hrs running in and out of town 3 or 4 times to grab crap. Heres a few pics. The truck ended up with a little bit of a rake due to the little bit extra on the axle tube, maybe the 15x8s instead of the 15x10s that are on the front, I dunno? The track width is also very close right at the moment and you can tell in the way it handles. My new wheels, better than the bling chrome ones I had /forums/images/graemlins/rotfl.gif I just sanded the rust down and gave the a quick shot of duplicolor flat black /forums/images/graemlins/thumb.gif Heres the diff itself, looks alright flat black I think. The blocks look gay but what are you gonna do /forums/images/graemlins/grin.gif Now I just need to do the disc brakes and get a front 3/4 ton under there.
