Mike, I wish I had read your tech page about two months ago. I just had my leaf springs powder coated and I’ve re-assembled the front springs with poly liners between the leafs. Am I correct in assuming that your advice for nothing to be between the springs also applies to these poly liners? If […]

Dear Mike, We met in Richmond, VA at the NSRA show last August. My car is a 1937 Packard convertible with Fat Man suspension and Mustang II coil springs. The springs had sagged to the point that the lower A-arms were not level but were going up toward each wheel. It had been suggested by […]
