What's in the Box

1973-1977 GM rotor redrilled to the 5 x 4-1/2" Ford bolt pattern. To be used with our #7024475 GM metric caliper adapter kit for disc brakes on a 1937-1948 Ford car spindle. Very common rotor to use as a conversion rotor. Has 1/2" fine wheel studs.

NOT interchangable with rotor 91031066. If you have brackets and adapters designed for the Granada rotor, use part #91031066.

Awesome product

July 04, 2014
Building a 1950 Ford F1 with a Jim Meyer weld in front suspension and this worked perfect for converting my front spindle from a chevy bolt pattern to a ford pattern. These fit perfect on the chevelle spindles that Jim Meyer uses.
Yes, I recommend this product.

The center hub is 2.78". In many cases wheels used on this rotor will be lug centric and will not fit tight around the center hub.

This rotor was never used in an OEM application with 5 on 4 1/2" bolt pattern. Dimensionally this is the same as a 73 to 77 Chevelle rotor but we have it made special with a 5 on 4 1/2" bolt pattern to use in our brake kits. This gives us the ability to offer more wheel bolt pattern choices.

Bearing and seal kit number 91031055 will be needed to fit this rotor to '37 to '48 Ford car spindles. Also you will need two bearing and seal adapters 91009301 to adapt the inner bearing size to the spindle.

We apologize but rotor number 91031067 will not be a direct fit to your 68 Ford pickup spindles. Speedway offers a kit for the earlier 48-56 but again we apologize it does not fut up to 1968.

Rotor number 91031067 is a 73-77 GM rotor redrilled to a Ford pattern. It will not fit the later G body spindle starting in 78 until the redesigned A body and then 82-88 G body. It may be possible with the correct bearings and races to adapt but the offset of the rotor in relation to the caliper would be the main obstacle to over come.

The GM rotor with Ford bolt pattern isnot a redrilled rotor, it is cast with 5 on 4-1/2" bolt pattern. Speedway offers bearing and seal kit part #91031055 that converts the GM rotor to 1937-48 Ford passenger car spindles and 1937-47 1/2 ton truck spindles
