There is a old man who drives through our alley ( goes through the dumspters) who drives a raggedy s-10 pickup, it has 4-15x7 looking truck ralleys on it. I know these are 5 on 5, and the S-10's are 4 3/4. I'd like to put a set on my s-10 blazer ( I have a set and don't like the vette ralleys on it )is it as simple as notching the holes or should the rims be re-drilled ? I tried to ask the alley can collector but there is a major language barrier. I am sure he probably had a buddy notch the holes with a torch. I don't want my ride to shake like the Flinstone mobile, possibly something for a machine shop to do? Anyone have and suggestion or thoughts before i chunk a wheel in the driveway and get out the rusty drill bits and Dremel?
