Been looking for several days. Only place that even hinted that they might have them is in UK. I don't have a complete machine shop and the local shops are all telling me 6-8 weeks minimum. I would like to finish this car before I die so trying to find some on somebodies shelf.:)

Any chance some crud got into the half-nuts and are not allowing them to close all the way?

that look s like it would not be to hard to make it. one piece of iron then cut it the hard part would be to get the iron to make it out of

I have steel in the shop I could make them out of but I still dont have a mill and a 7/8x8 acme tap is 160 dollars. That is quite a bit for a one time deal. However, there is a Bridgeport knee mill on a auction sale this weekend:3dSMILE: . I really regret selling my mill when I moved. At this point, I may wind up making them with a file and die grinder.
