Thanks TR3.
I did find the parts from one of the usual suspects, they are on order.
A local corvette mechanic, amongst other machines as well, has looked over my shop manual and will be doing the work for me.
I do not have a good place to lay up the car for a long time to do it myself, nor do i wish to attempt it without a jig. be nice of the shop manual to give one dimensions for making these tools.

I will post again to let y'all know of the results.
apparently not a typical proceedure. yours is the only reply. i do notice that quite often, many viewings but few replies to a lot of subjects. do we have mostly lurkers here?
