I wanted to start a thread detailing the changes planned for the rear differential of AK1085.
As most of you may know these cars come with a 3.07 rear end which is a bit anemic for use in a cobra type vehicle.
Considering many modifications around the motor, which is a 302, there are a plethora of offerings however you’re still gonna be plagued by the fact that the rear end gear is 3.07, fifth gear is not attainable until over 85 miles an hour currently.
Common sense dictates the changing the rear end from a 3.07 to a 3.54 should help delivery of the power it currently has.
So with the help of Mitchell’s Differential, I took a Diffy from another MKIV and modified it with all new gears, seals and bearings taking it to a 3.54 retaining the original posi-traction rear end.
I also have a 3.31 getting re-bearing and re-sealed for possible use of the 3.54 is not what I like.
Never hurts to have spares………..
Before install I will paint it red with the rear cover black so it at least matches what they once were.
