Howdy and welcome to me -

Being new to this forum, I am trying to find the answers to my few questions.

First - I have a 1934 Ford with stock frame.

1 - I need a 58 inch hub to hub Ford 8.8 inch rear end - Posi trac - about 3:50 range
gears.

2 - What Ford would have that measurement width with posi - trac for my project?

3 - What is the difference between the Ford "tru loc" and the GM "Posi-trac".

4 - Since I want BOTH tires to connect at the same time power is added, which type
of Ford locking rear end should I look for? They have several - Air lock, Tru lock
limited slip, etc.

Appreciate any and all honest help.
