I checked the pn on my springs, and hope they are correct.
convertible 340 4 spd 323 gear. I cant find the codes anywhere to make sure. Is it correct?

Is it really necessary to re-arch them? I was thinking of just wire brushing them and putting them back on, bare steel. I just don't know if springs naturally fatigue.

I plan to run L60 polyglass goodyear in the back, and re-install the day2 air shockes that raise the car in the back (if needed).
