I am wanting to know what range of gears are available for this rearend or if any other third members will inter-change with a two speed set-up.

An over-drive transmission is an option but would rather not go that route if I don't have to.
Only other Timken C100 ratio offered: 5.29-1. Eaton model 1350 two speed also available for 1951/52 F5/F6, 1953/56 F500/600 with 5.83/8.11 & 6.33/8.81

TDAA-4209-C .. 5.29-1 Ring & Pinion Kit / Obsolete

GREEN SALES CO. in Cincinnati OH has ONE = 800-543-4959.

No Ford Dealer, no other obsolete parts vendor has any.
