Hi Dan; that does look like the Fulton HD25000101. Lining up the ruler with the bevel it looks like it is 1-5/16" wide just like the gear that comes with the # F0933306S00. Take a look at the dimensions for the parts below and see if that all matches up. Assuming it does it is safe to say this is the right kit for you.
Gear Bevel: 5/8" thick x 1-5/16" wide
Pin Spring: 3/4" long x 1/4" thick 0.230
Washer: 1/2" inside dia x 1-1/4" outside dia
Spacer: 1/2" inside dia x.63 outside x 1-1/4" long 1.30
Groove Pin: 3/16.1875 thick x 1 long
Bushing Flanged: 1/2 inside dia x.70 wide x.94 long
