In my hunt for a good used 1/2 ton for a daily driver I came across and bought a sweet '99 Gmc Sierra 2500 2wd reg cab with only 60000 miles. It's got the 6.0 which is nice because I was having trouble even finding a 5.3 in a 2wd truck. On the down side it's got 4:10 gears which are not good on the highway. My plan is to swap in a complete good used 3:73 rear end (which is cheaper for me to do myself rather than pay someone to change gears in the current rear). I just came accross a guy with a wrecked 1500 with a 3:73 rear. Only thing is it's for 6 bolt wheels, not 8 bolt.
Here's what I'm wondering. If I use this rearend I could probably get a good deal on the 4 6bolt wheels and the parts to convert the front to 6 bolt hubs. How hard would it be to change the front to 6 bolt hubs?? I'm hoping I can use the existing spindles and just change the hubs. Anyone know?

Well I've come to my senses now. After thinking about it I think I'd be going to a heck of a pile of work in order to use parts off this guys 1500. I better continue looking around for a rear out of a 2500 to swap. Either that or learn how to swap out ring and pinion gears.

At the risk of appearing rude, it might be cheaper in the long run to pay a WELL RECOMMENDED pro to install the gears for you.

It being a 1999 ... does'nt it have a OD transmission ??
There is NOT a lot of difference RPM wise between a 3.73 and a 4.10 ... with the large tires that came on a 2500 series truck
