Rear Hub size for spacers?
Hello all, used to participate in these forums with my 71 C10, have since changed and moved on to a different project, an 89 Jimmy K5.
I've done a front spindle/bearing, wheel bearings, brake pads, rigged up the back window track etc.. so far. But when looking at it, the back wheels are inside the fender and the front wheels are even with the fender, so I was going to put some 1.5-2 inch spacers on the rear to bring them even with the front. Everything says they should be 78mm hubs on the rear, so I ordered a set. They're way too small. I start looking some more and it seems like 87 or 106mm are my only two semi-standard options. I get out a tape measure, and the rear hubs are 3.5 inches, which translates to just about 89mm? So I guess my question is, did someone change the rear end, and what are the odds that the 87mm hub centric spacers will actually fit on my rear end? Really looking forward to getting this project going. Thanks! Happy to be back. https://imgur.com/IZP39pw

Re: Rear Hub size for spacers?
89 k5 is still a 73-87 body style and parts .
Yes rear width is 1.5" per side narrower to help the turning circle radius . Not sure on the hub center size as i play with 1tons mostly and dont recall 1/2ton specs .

Re: Rear Hub size for spacers?
The general summary is I'd like to avoid Lug-centric spacers, which seem to be much easier to find and am wanting to know if anyone has used 87mm bore spacers and they fit as they should.

Re: Rear Hub size for spacers?
You should ask in the 73-87 section where those with your body style will be more likely to see your question.
