The two that I have that are cutlass both have the rubber layer but this one does not. Did all f-85 and Cutlass have the rubber? Till now I thought everything in 62 had it. I would assume this to be the original but I can’t say that for sure. Only had 44,000 miles but I guess it could have had one brake maybe and got replaced. I would suspect they had a running change and maybe this was just the early 4 speed setup. I may just change it for the other larger Jetfire shaft I have. Not sure what way i will go on this yet.
