staledale Posted October 2, 2003 Share Posted October 2, 2003 I trying to buy a set of adaptors for my Dayton wires, the guy selling them said it is 4 1/2 bolt pattern and they fit a Chevy. I've always known chevy as 4 3/4. I know that if you measure center of bolt to center of opp bolt it will measure 4 1/2, but did Chevy change the bolt pattern in the past few yrs? I can get a hell of a deal if they work. any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
dmyntti Posted October 3, 2003 Share Posted October 3, 2003 I believe Chevy used two different patters one 4-3/4 for Large Cars (i.e. Chevelle, Caprice, etc.) and 4-1/2 for smaller cars like the Nova. I hope this helps. Quote Link to comment Share on other sites More sharing options...
Mike kZ Posted October 3, 2003 Share Posted October 3, 2003 No they didn't. It's 4 3/4" for almost all the Chevy line. The large Caddys, olds, and maybe mid 70's Impalas were 5" Quote Link to comment Share on other sites More sharing options...

Trevor Posted October 6, 2003 Share Posted October 6, 2003 Some GM front-wheel-drives are 5 on 115mm, which is close enough to be confused with 4.5". Quote Link to comment Share on other sites More sharing options...
