I have been looking locally and thru lots of parts catalogs for a set of extra long shank 7/16 lug nuts for my 89 k5 jimmy. With my stock wheels and center caps, those short lug nuts are getting chewed up pretty bad. I've also noticed, as I'm sure many of you have, the rear GM 10 bolt is not as wide as the front axle. I read somewhere that it's approx. 1.5" shorter on both sides. I was thinking about wheel spacers on the rear end to even things out,however, I have had no luck with this either. Can anybody steer me in the right direction?
