Ordering KITT's Differential, Gears And Axles

The next thing I need to concentrate on is getting the wheels back on the car. I have been waiting on a guy that specializes in rebuilt differentials, axles and gears, but after three months he has not been able to produce the parts. I decided to give up on him and on Monday I ordered all of the parts I am going to need to rebuild KITT's rear end.

When it came to the limited slip differential I wanted to go with the best. The Eaton Posi is supposed to be the best there is, and is fully rebuildable. 

With the gears I wanted to find a good balance between power and fuel efficiency. The 3.42 seemed to be favored, however since I plan to take KITT on a lot of road trips, I opted for the 3.23 gears. They will provide much better fuel economy at highway speeds with just a slight loss to off the line power. 

I also upgraded to the stronger 28 spline axles versus the stock 26.

Here is everything I ordered:

Eaton Posi Limited Slip Differential

Brand: Eaton Torque Control Products
Manufacturer's Part Number: 19599-010
Aftermarket Carrier Style: Limited slip

Spline Diameter: 1.20"

Eaton Posi prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases, clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel. Eaton Posi units are rebuildable and made in the USA.
