Hey all if I cant find the answer here then I wont find it anywhere ! I bought a set of old Ansen Top Eliminator wheels for my 61 Pontiac wagon. Big Pontiac is a 5 on 5 pattern. My problem is 2 wheels are 5 on 5 Pontiac and 2 are 5 on 4 3/4 Chevy. They came off a 55 gasser with a Pontiac rear end. Is there a way to open up the 4 3/4 bolt patter to 5” ? Anyone know a machinist that has done this ? I love these wheels and doubt I will find a pair with Pontiac bolt pattern so trying to use what I have.
