Hi grannyknot i have almost the dilemna as you have i bought my latest Z November 2010 it is in very good Shape it is a early 71. It was modified by first owner he was usng on track only so it as a rollcage improoved suspension and brakes but from back then the only thing i had to change was the twice pipes that i canot run on the road in Canada so i chenged it. the car as less then 60000miles i know that i want to repaint it. I know that i will change all the bushings I am juggling do i reupsol the seats or do i change them for Racing seats etc... I am not sure yet... my heart say tweak it with todays performance parts. but but but...
