Joe,
Thanks for your inputs. Am I correct in assuming that the 10-1/4 inch
measurement is the unloaded height? Also, Nolan said his 2 coil count was
very "unscientific" - just 2 loops from the start of the spring and cut. Is
this how you counted your coils? There's another guy in MD whose website
said that he cut 1 or 2 (I've forgotten exactly now, but the number is not
important) *ACTIVE* coils, which I would assume to mean he's loaded the
spring and then counted his coil(s) from where the coils begin to seperate.
Comments?
Thanks a lot!
George P.
