So I found the lengths that will work. And I know the threads are 4-40 type. I can't seem to find the diameter anywhere. And pardon my ignorance if the diameter is implied with the 4-40 thread type designator. Will they fit the Gen I Traxxas rod ends?
I'll sign off with the ol' "thanks in advance"!

Rad! Thank you for your time and attention regarding my inquiry, Sir. Google by proxy. I knew I should have looked a little harder.

The retro turnbuckles start with a 1/8" rod that is turned/rolled with #4-40 threads on the ends. As shown above just under 3mm
