Both NAPA had the drive shaft shop had replacement parts (Ross - I don't recall the brand) that were listed as the same 4635 however, none of them had enough clearance.
My 1948/56 Ford Truck Parts Catalog (final printing 1964) lists
B7AZ-4635-A for both front/rear. All 4 cups are #1270 size.
My 1975 Ford O-S-I (Obsolete-Supercede-Interchange) catalog shows that B7AZ-4635-A was replaced in 1963 by C3AZ-4635-E. All 4 of these cups are #1310 size.
But FoMoCo sez this u-joint will work on 1948/52 F1's and 1953/56 F100's. If you want what is listed in the 1948/56 catalog:
B7AZ-4635-A =
CARPENTER
NOS OBSOLETE PARTS in Concord NC has THREE = 800-476-9653.
ANTIQUE AUTO SUPPLY in Arlington TX has FOUR = 817-275-2381.
