Hi all,

Thanks

Mine measures 7.625 (7 1/16) overall diameter. The raised portion in the center is 1.875 (1 7/8). Hope this helps.

I'm not sure of the year but based on the backside of the center section and the 1 3/4 inch brakes I believe it is pre 1968.

Thanks Bill, I thought that's what it was. Knowing for sure will help when I eventually replace the brakes. I already upgraded to a Tru Track and 31 spline axles.
