The Stovebolt Site Forums The Shop Area Driveline 1942 (BL) 3/4 Ton Rear End Swap

Thanks for your help.
I really would prefer to go with the 55-62 differential swap as described in the tech tip. Since my OE diff is 4.56, even the 3.90 would be a significant improvement. It sure would be a lot less work than swapping out the entire rear end.
All I want to do is put in some taller gears that will allow me to cruise at 60-65 without making my 62 235 scream it's guts out. This motor has dual Rochesters, Offenhauser intake, and Fenton headers, so it will handle the speed but, I don't want to push it to 65 with the OE 4.56 gear ratio.
I'll also look into the OD trans set up to see if that would be another good upgrade for my truck.
Thanks once again for the tips. While I've done several cars in the past this is my first truck mod, so I really appreciate the input.
