Nikon AI conversion

[RalphLambrecht]

Possibly a dumb question, but important to me. Hence, I ask:
I got a perfect non-AI lens coming in the mail. Also, I have an otherwise defective AIS lens sitting around doing nothing. Can I remove the aperture ring from the defective AIS and mount it on the non-AI to convert it to AI, provided both lenses have the same aperture range?

Unless the lens have changed physically and mechanically from non-AI variant to Ai/AiS variant.

to clarify, these are two completely different lenses; one is a 105mm f/2.5 and the other is a 24mm f/2.8

No, you can’t.

I don't think that would work. When prices got low enough and there were different Nikkors to choose from, I just got both. When using a pre-AI lens with a Nikkormat FT3, I just flip up the AI tab. Using an AI lens with a prong on a Nikkormat FT2 is no problem. In the past, John White did some conversions for me. I have enough different Nikon film cameras that I don't think I would bother getting any more Nikkors converted. My 28/2 Nikkor is a 'K' model but I have used it in stop-down meteting mode with a Nikkormat FT3 successfully.
