What's inside depends on the lens model

for AIS lens ??

You'll be needing either photos of that exact model or you end up deciding to disassemble your own. On this picture of a different lens note that the aperture lever assembly is attached to the flange (some different models I took apart were not like that), and that there is a brass adjustment shim that was used to set the infinity focus. You might not be surprised but be prepared for it.

The screws are hard to remove because of some really gunky factory thread locker compound that probably has gotten even harder with the passage of time. Be sure you have a correctly sized screwdriver, apply firm pressure to keep it from slipping out and mangling the screw head, and be patient as you twist.
