Thanks to all. I will contact Tom from FE's. To be honest, I would rather go with Kirkham's diff, what I saw, be it on the ground, looked very nice.
I just got back into town from UT, Daughter graduated from College yesterday, BYU in Provo, my wallet feels heavier already
Kirkham's shop was less than 3 miles from our hotel. They were building 4 cars and had about 12 bodies stacked. Talked with tom and his mother, great people!!!! I didn't realize that they fabricate a lot of their own parts, he took me in the back shop where all the machinery was and saw a pin drive hub being lathed out a solid piece of billet aluminum, very cool.
