Wanted: HP7970 hub mech

I didn't even know there was such a thing as a twist to tighten on the HP7970. On the 7970A maybe?

The quick-release levers on the HP 7970 tape drive are plastic. They're starting to get brittle. I've got one that's showing cracks, so I swapped it the the one on the takeup reel, as that one doesn't see as much action as the one on the supply reel. What I'd really like to find is the older twist-to-tighten mechanisms on the 7970. I suppose I can get busy in my shop and make some, but I'm wondering if there are any lurking in someone's hell box. Thanks for reading! Chuck
