If it's a 10 spline Ford from the era, it will fit. Even if it were a 6 spline, it could be made to fit with a 6/10 adapter coupling. Importantly, all Ford gear sets of the '32-'53 period are matched sets, the ring and pinion must not only be of the same ratio, but must both carry the same hand etched serial number. Mixing a ring from one set and a pinion from another can result in rapid wear.
