Outer 1.125 inner 1.025 approx. Material approx .035 thick
The is from a used one so may have some wear. The inner would just be larger then the spring diameter.
I know the voices aren't real but damn they have some good ideas! :shock:

Thanks. I'm hoping it will fit my 1915 Overland.

Another choice might be Chevrolet. Up to 1928 at least they used a flattened cotter pin type pin. So the seat would work somewhat the same as Ford and would be a little larger. I will check the diameter of the spring later today and post the info.

The Chevrolet (1928) springs are approx. 1.200 in diameter. Subtract about 3/16 for the inside diameter. The other difference is the Chevrolet keepers don't have an outer rim, like the Ford ones. If you look close at the photos in the link you can see them.

Phillip if you need the 1928 Chevy ones I have plenty of serviceable ones.

All the Best,

Hank
