Maybe all those Mech Eng. classes did some good other than increasing my debt to income ratio.

CORRECT CORRECT CORRECT!!!
During the C&T, you MUST heat the outter tube to rotate the inner tube. I've heard of guys doing it without the heat, but they must be stronger than me. In the 3 C&T's I've done, I used a 6 foot cheater bar and we still needed heat. All that heat is what distorts the grain stucture of the metal weakening it. Also, just remembered, one of the companies (maybe all-pro) has the gusset kit also but it put the shock in double shear instead of single shear like the picture i posted a few minutes ago. The double shear shock mount is also a good idea if you're trying to do it right from the git go. I've seen shocks in single shear bend bolts pretty badly.
If my memory serves me correctly, Toyota put the inner and outer tubes in a .007 interferance press fit (pretty tight)
