"I can tell that Dave has "been there & done that" with the Fords! Changing axles and transmissions on pre-49's isn't much fun - I think I broke and repaired 6-7 transmissions and a couple of axles. I do remember beating a couple of Chevy V8's, though."
With the non-banjo rear ends (49-51) the trick was to take a broom stick and put a wire loop on the end. Reach inside and drop the loop around the broken part and pull that end piece out. I used to remove about half of the cross member bolts because I broke transmissions so often. They would never break when you were abusing them, it would go "Tink" when you were on a date or something. The engines were great.
