Auto Chinon lens mount trimming

Jut bought an Auto Chinon 35-80 mm, f:3.5-4.9, in excellent condition, I'm planning to use it on my pentax K-5, but the lens mount needs some trimming, in order to fit properly. Any ideas, how to do it, so the optics, mechanics wont be damaged? I mean, if I use some kind of saw, maybe some metal particles might get into the lens body, obstructing the optics, mechanics, etc. so, if I'd have a better option, I'd avoid the previously mentioned one.

Can you post an image of the lens and mount ? I do not understand what you need to "trim" ... the aperture protection ... J

Assuming it's the lens as shown on https://www.flickr.com/photos/kurotonohage/sets/72157631349939700/ , you can probably take the mount of and remove the flange that protects the aperture lever after that.

Just a set of precision screw drivers (probably JIS, but small Phillips might do if the screws are not too tight).
