I've tried searching but can't find anything on this. I need a replacement arm for what I think is a JT580 (NOT the low profile one). It doesn't have a collar on it, it's just a straight screw in arm - the one on my JDR94 fits it but I need another one.
Here's a pic of the bridge, it's on a Stealth (which should have a JT500 but this is a JT580 I believe).
