I know that the 770 & 970 use those sizes. I think that the 750 may have also. No idea if the patterns are correct. I've re-drilled rims (kubota ? to deere 750) to fit before and i did a post on it, but I don't remember which section I put it in. It wasn't that bad, so if you can't find a pattern match, I would buy the best deal I could find and re-drill them.
