Scroll down to step 5.

I have done it this way so many times I lost count. Never scratched the rear element.

If you feel you must remove the ring, that is fine, but you will want to use a file to remove the material.

Also, on most 5D and 5D2, you need to reduce the ring as much as possible AND grind the mirror to achieve infinity.

I you want to send it to me, I will do the retaining ring reduction for a very small fee. It takes me only a few minutes.
