Can I adapt an M42 lens to Nikon F without removing the original mount if it already focuses past infinity?

I have several older M42-mount lenses and I’m trying to use them on a Nikon D3200 while keeping infinity focus. On one lens I replaced the mount with a 3D-printed Nikon-compatible mount and it worked well.
On another lens, I was planning to remove the existing mount plate, but when I test-fit it against the camera it appears to focus beyond infinity already. Before taking the lens apart, is there any reason to remove the original mount at all? Would a very thin M42-to-Nikon F adapter be the better solution in this case?

I can't help you with disassembling that lens but since that lens will focus beyond infinity, I would either buy, or print yourself, a thin M42 to Nikon F adapter.
You can buy one like this for under $5.00

Generated from our catalog & community — verify before relying on it.
If the lens already reaches beyond infinity on your Nikon body, you likely don’t need to remove or replace the mount at all. The simplest solution is to use a thin M42-to-Nikon F adapter.
That’s the key point from the community reply: since the lens has enough register margin to focus past infinity, a thin adapter should let it mount properly while still retaining infinity focus.
Disassembling the lens mount is riskier and may be unnecessary unless you have another specific reason to modify it. If the goal is just to use the lens on your D3200 with infinity focus, an adapter is the cleaner approach.
