Good morning All - I was lucky to find a decent 52 F3 that ran, kinda. There are some issues with the transmission and rear end. I have read where many have upgraded the rear end of the old Ford trucks with the more modern Ford 9" rear end. I was fortunate to locate an original 9" from a 64 Ford F-100 for the sum of $50. My questions are centered around the modifications necessary to put the 9" into the F3 and the alterations need to change to a real drive shaft. My thanks in advance for the assistance! If there are any participants who need an original F3 rear end, I might be your guy.
