The one I took off (the '72 coupe) was the original and was hard as a rock and cracking. Csaba from AR found an OEM hose, and I struggled to get it on for an hour with no luck - just too hard and the ID was way too small. So I called and he and Ramzi suggested I boil it. So my son and I waited until my wife was gone, stuck it in one of her prized pots and boiled it, went out to he garage, and it slipped right on with virtually no struggle! 10 minutes later it had cooled and shrunk, and was sealed tighter than any clamp would ever seal it.
And we got the pot back in the house, cleaned up on the shelf again just as my wife pulled into the driveway. Phew.
