Thank you DMT
I had bought the bellows type boot that seals the clutch pivot arm to the bellhouding from another vendor. It was so flimsy that it collapsed, got sucked inside the housing and got chewed up by the spinning clutch. After thst I took the remains out and replaced it with the hard 50 year old original.
I saw DMT at a Columbus Mopar show and they had the same part, but different. Jim let me borrow it (without paying for it mind you) to trial fit it into my "new" slant six 4 speed bell housing that was in the trunk of my SUV. The DMT part actually snapped into the rectangular hole in the bell housing and it's staying there. I was more than happy to go back and pay them. It easily is twice the thickness of the failed flimsy piece that didn't really fit the shape of the cutout anyway.
I always talk to these guys at shows and am impressed by their enthusiasm and quality of their parts.
