These are off my TOA-150. For some reason the bottom mounting plate on one ring is shorter than the other (See photo)

I am ordering a pair of Parallax rings to get around the issue. I only realised the difference recently, and now it makes sense why one ring was always harder to tighten than the other.

They are 179mm in diameter, and sell for around, $600 USD. Im not looking for anything near that price tag. If someone can use them, make me an offer.
