So, trying to find dimensions of the eccentrics from a miata. See if they will work for my neon. Cant seem to find the original ones anymore. 

Anyone have a loose one laying around?

Diameter of the eccentrics,  size of the bolt (m10?), width between the eccentrics.

If you have access to a milling machine you could cut the grooves for the eccentric several more (about 10mm) millimeters before you run out of thread. See Accordionfolder's pictures.

Im looking at 35-36mm beyween the lobes of the eccentrics. 

M12 bolt, or m10

31-33mm eccentric diameter. 

 

So the miata bolts are just twice as wide as i can work with. Otherwise perfect. 

Unless tgeres a way to thread and mill them significantly more that im not seeing,  or a grm'er with that ability.
