I am of a mind I'm calling Ames now to check the dimensions of the rubber style. My OEM pads look like the ones they have listed for the 1967 lower pads. I just replaced my body bushings w/ urethane also. Hoping I don't hate it.
I somehow ended up w/ 3 sets of urethane spring pads. How many do you need, maybe I'll just send you my extra set.
