[DeTomaso] Attainable 70's muscle cars, Mach 1

[asajay at asajay.com]

Two things.  First, it's an appearance thing, but if I put acorn style  
nuts on, then I can't see the difference.  Second, in some racing  
venues, they want to see how many threads (or as you point out) to  
what degree the stud has been engaged.

Somebody with more smarts on this subject than I would be better  
qualified to answer the question of if I really need longer studs or  
not.
