Just to let everyone know, I just got done with the mod and no worries. I discovered the "Ricoh pin" that can get jammed in the AF drive hole and removed that from the lens as well. I put up a few pics of the process:

Reassembled lens with hotglue covering the Ricoh pin hole (sans plastic spacer), and screw thread hole. Also, the ridge has been touched with a black sharpie.

I found out one has to be careful or the aperture sens pins might fall out.... Fortunately I found it... :)
