Thanks for the reply!, I did some more research and saw that too, looks like this is not going to be an easy swap, 31 11/16" axles, 31 13/16" axles, .176" c-clip groove, .208" c-clip groove, will my new Auburn work?, maybe I should just get some billet aluminum wheel adapters and quit obsessing over it! 1.25" per side will not cause me any clearance issues, and this is just a street toy, no heavy loads so I think I should be fine.
