Hey Mike,

Here are some measurements and I will load some pics later?

Alloy ring. OD 87.1mm, ID 66.9mm

Stepped rubber mount so the ring sits on it. Outside rubber could be trimmed to be flush with the ring (hehe...ring). OD 93.8mm, ID 50.4mm.

Rear leg ring is ovalised for the angle. The rubber mount has more excess past the ring. I would guess this is to hide bigger hole cutouts for mis-measurement. Again, this is easily trimmed.
