I hate calling guys honey:

My older Q-35 had a sticker on the face of the mag rotor and I thought a very small size stamping on a side below the fins. Can't check for sure since I traded it for a G-38.

Oops, after 20+ years I remembered I had a parts 35 downstairs. Mine doesn't have any size stamping on it either. If you can give me some dimensions, I'll compare it to this one.
