Hi, can someone please confirm the length of the very long stud that goes through the frame and the two front footrests attach to.

I think it is part number 66-4900 and i think it is 13 7/8 in length and 1/2 inch round. Is this correct?

Hi Brandon,

My original measures 14-1/4 inches long. It is 1/2 inch diameter, and 20 tpi. 1/2 inch Unified Fine Thread and 1/2 inch BSCY are the same. 7/16-20 Unified Fine and 7/16-20 BSCY are also the same.

Generally speaking, the studs are about 1/8 to 3/16 inch longer than the assembly leaving about 2-3 threads proud of the nut. Generally.......

I hope this helps.
