Hi, John,
As I tend to buy these a dozen or so at a time; and haven’t ordered any for a while, I don’t know what their current supply is like.
That said, and only FWIW, I have found that it’s often much easier to use those bushings if one also replaces the pivot rod with the newer, marginally smaller dimension one. The while the old rod doesn’t need replacing because of wear (unless, of course,it does), its larger diameter can make installation of the new bushings an exercise in frustration.
If someone else has a better solution, I’d love to know it!
Kind regards,
Horace
