What front coil and rear leaf spring configuration are you running?
I recently put on koni shocks, a Global West 1" drop 640 coil and poly bushings. I've yet to replace the rear leaf because there's so many to choose from I'm lost. My car is a Jan 65 hipo from Dearborn.
Right now the front is sitting with a ride height of:
Front: 26 5/8
Rear: 25 1/2
Hopefully replacing the rear leaf will even out the dragg'n butt and high nose! Any suggestions. I'd like some close to the original ride set-up. Once the rear is done I might still end up replacing the front coil with a more factory option, because I'm getting a bit worried the car is still going to sit a bit high for a stock K car height.
