Thank you sir for that offer to make them. I managed to find a set from Corvette Central. They are on their way. I will measure them carefully against the old ones I took out. If they work, no problem, if not I will let you & Mr. Don know. Looked like the original top bushing may have been removed at some point and replaced, without a bushing driver. Only reason I say that is because it is mushroomed just enough that the retainer landing is out of shape and the retainer let go.
Merry Christmas,
Sean
