39 Ford 3/4 & 1 ton axles.

[popcorn-guy]

It seems that there has only been one year that one can obtain hyd. brakes and a closed drive line and that being 1939. As far as I've been able to discern. One individual indicated that the 3/4 & 1 ton axles were the same and I would like to know if they both have a full floating axle or a 3/4 type?

Anyone out there have that information? It would go a long way towards converting an AA to hyd. brakes and retaining the stock appearance.
