5x5 to 5x4.3/4 Bolt Pattern

[198plus]

I'm wanting to go from 5x5 to 5x4 3/4........I have 86 spindles and have the large rotors, if I remember right they are 11.86 x 1.25. I would like to use my same calipers and spindles..... So I'm wondering if there is a rotor I could use for this swap. I don't want to re drill them. Any help would be great, thanks.

The only 4 ¾ option I’m aware of is a kit from CPP but it only goes up to 1970 spindles. If anyone ever finds a combination of bearings and 4 ¾” rotors that slide onto stock truck spindles I’m sure it would be extremely popular. So far the only 60-66 trucks I’ve ever seen personally with that pattern in front had a Mustang swap.

Some of the Impala's and Caprice rotors will work with the same bearing, but they are 11" and 1" wide. I really want to use the 11.86 and 4.75 rotors. Let me know if you think or anything. Thanks

The only thing with having them re drilled is you have to grind down the webbing inside back of the rotor, to get the new pattern in.

You would think someone would make this swap.... It's a shame I can't get the wheels I want in a 5x5.

I just drilled mine front and rear for the 5 x 4-3/4 no big deal, it worked like a champ.......
