Made a dumb mistake today
I had been looking for another rear end for my truck to convert it from 6 to 5 lug. I already have some rims that I want to use so I started measuring how I wanted the wheels and tires to sit in the fenderwells. I found a guy selling a late model z28 rear end with posi and disc brakes that just happened to be the width I was looking for. I got the rear end home and started to stick my rims on it and they dont fit. I didnt think to check the bolt pattern. I just assumed that chevy 5 lug were all the same. My rims are 5x4.75 and these are 5x4.5. UGH!!!

Re: Made a dumb mistake today
actually your wheels should be 5x5 and the rear end should be 5x4.75
![]() but either way, adapters or getting the axles and rotors redrilled to the pattern you need will work |

Re: Made a dumb mistake today
The wheels are 5x4.75 and the new rear end is 5x4.5. I cant do adapters because they will widen the rear end too much. I think I am going to just have the axles redrilled.

Re: Made a dumb mistake today
All older Chevy trucks are 5x5. Most GM cars have the 5x4.75, except I know the 91 and newer Caprices and Impalas are 5x5 also.

Re: Made a dumb mistake today
I agree with the others, truck 5 lug wheels are 5x5, Z28 rear ends are 5x4.75.

Re: Made a dumb mistake today
That makes sense. Either way I still have to redrill the axles or change out the axles.

To be safe take a wheel with you when you take the axles to be drilled and let them measure it... LockDoc

Re: Made a dumb mistake today
Or sell the wheels and get the ones that will fit.

Re: Made a dumb mistake today
Not to mention that z28 rear end is a 7.5" 10 bolt. These are very week rears and I would not trucst one in a truck, if you plan to do more than just cruise.

Re: Made a dumb mistake today
Actually Caprices etc. bounced around on size from '71 up, some years had both sizes. I have had a '72 Grandville, '77 Bonneville, and '96 Caprice with the 5x5 and I had an '86 and an '88 Caprice with the 5x4.75. In the words of Shawn Spencer from the TV show Psych "I've seen it both ways".

Re: Made a dumb mistake today
I've been measuring the 5 lugs wrong! I always take a rim though. I've screwed up enough times with centers being too small or the pattern being smaller or bigger that I always take a rim.
