I am trying to put on a set of stock aluminum wheels from a 2001 3/4 ton truck on my 91 I'm assuming the bolt pattern is the same but my question is the lugg nuts because I want to use the factory center caps and they are held on by the ring on the lugg nuts. The lugg nuts from the 01 are 5/16 I think but the ones on the 91 are 1/2 and I was woundering if anyone has found a set that has the ring for the center-caps and is 1/2.

 

I did this also.....you need some special lug nuts. They ended up costing me about 40 bucks....check the sticky, there is a thread in there with a NAPA p/n that will hook you up. I googled the NAPA p/n and found places on the internet selling them cheaper.

They gave me a mil discount......and these work perfect.
