Did mine today. Looking at the keys I took off... the ones I got from Seed60, and another set from a 99, the guy who was helping and I couldn't tell the difference in the keys. All three of them were clocked the same. I'll see if I can get a picture later of what I'm talking about.
Also upgraded to #1 bars and chevy drop shackles.
Before: T bars only cranked 1/2 way
After T bars cranked with only 4 threads left
Also, I used 2/3 jaw puller.
(picture doesn't represent jaw puller used today. this picture was from a weekend failure)
But if you notice, the stock torsion keys is clocked where as the one Dallis posted isn't.
