I pulled the steering box out of my ‘59 F250 4x4 and it’s pretty loose. The casting number on the box is 4CC39. I have a good box out of a ‘58 F350 2wd that’s has a casting number 4CC25. I’ve read that the 4x4 box is different than the 2wd but they look identical. Does anyone know if I’m ok to use the ‘58 2wd box in the ‘59 4x4?

B9TT-3504-A .. Steering Gear Box (no housing casting number listed) / Obsolete
1957/58 F350/600 / 1959 F350 except with Saginaw steering box / 1959/60 F500/600 / 1960 F350.

F100/250 4WD uses the same steering shaft as F350 (B7Y-3524-A), but the 4WD's sector shaft (B7T-3575-C) is different than the F350 sector shaft (B7Y-3575-A).
The steering shaft bearings (2) and upper/lower cups (1 ea), sector shaft bushings (2) are the same for both.
All 1953/78 F350's are 2WD, 1979 was the first year that F350's were available with 4WD // If a 1953/78 F350 has 4WD, it's an aftermarket conversion.
So I measured everything up and the sector shaft is identical. However, the mounting plate is slightly different. One hole won’t line up. Nothing a drill can’t fix.
