I have 2 or 3 different 510 J rods, that are "clocked" differently........must have been early vs mid vs late production............??  If you can tell me or send a clear pic of EXACTLY what you need, I can likely help!  Unfortunately, I can not tell you what you need.

I might even have one of the Z/ZX "slider" J rods..........??  They are cool, cuz you might not need to weld anything, as the J rod extends and compresses........depends on how you set it up!

By "clevis", do you mean the fork on the throttle shaft of the OEM carb?  Yes, I will also have that.

Let's figure out the J rod.............

If pics are easier via email, send to yenpit@hotmail.com 😎

The ones on the 710 were telescoping. You need that for  SUs.
