Can someone tell me the thread size of the radius arms, I need to chase the threads and I do not have a pitch gauge. Thanks for any help

I believe the radius rods threads are 9/16-18.

I just had the same problem. Save yourself some heartache and buy a two piece die that will "clamp" on and dig into the good threads. https://www.jmeinnovations.com/

Here's a good option from amazon. 9/16-18 Split Die Thread Chaser https://www.amazon.com/dp/B003H2JWOI/re ... YCbF7FBCRJ
