I have a set for a 2000 4x4 dually I will sell also..... decided I really dont need them as 95% of my driving is in town @35 MPH. I don't know if they will fit the older trucks as there were a few different wheel offsets used. I don't think the 3rd genners will work though as they are for 17in wheels.
I'll let em go cheap if you want em.
Edit:
The fronts are the same for 2nd and 3rd gen..... rears are different.
