jt-500 trem anchors...schallers same size?

[mutex]

Hi,

I have a used jackson that im 99% sure has a jt-500 trem. Its got the same finish as ones ive seen in the pics, and has no logo on the side.

I was trying to figure out why it wont stay in tune, and took the trem apart. The anchors in the body look like they were stripped and (badly) repaired with thread inserts. The trem studs move around ALOT, about 5mm worth.

Im just going to pull these and put new anchor/studs in. I havent pulled them, but I measured the existing anchors still in the body at 9.8mm. Im assuming theyre 10mm once removed and the wood is covering them slightly.

Ive read that the schaller anchors fit jt-500 trems, but ive seen a few different schaller anchor part numbers and want to make sure this what I want:

Those are the OFR posts and inserts, not sure if the inserts are 10mm though. Check the Stu Mac website, I think they give info on the hole diameter needed, etc.
