Hey guys and gals, I am swapping out the 289 out of my 67 and replacing it with a 390 I picked up. I know the frame pads are way different. I am having a problem running down the frame pads. Is there a company that reproduces these parts or does anyone on here have a set that they would like to let go for a fee? An correct me if im wrong but 66 through 68 fame pads will work wont they?
