It looks like someone just cut a cross member out of an old Ford car and chicken scratch welded it in or tack welded it since it's not tied down worth a damn. Using an old cross member can work but some folks need to learn more about fabricating things and getting sound structures together.

I am a flathead fan myself so all the other stuff may give more power but those old F1 pickups were classics just the way they were from the factory. The F2 & F3 pickups are another story. Stuff is getting hard to find for those old Timken Detroit rear axles and the brakes. They are better off with upgrades. A person should be able to find a rear cross member but folks are using them for AV8 hot rods these days. It will take some searching but they're still out there.
