Disassembly of the Vivitar (Pentax K) 75-205 3.8 lens

I have a trouble. I need to remove the diaphragm pin for using Vivitar (Pentax K) 75-205 3.8 lens on a DSLR camera. Can anyone suggest how to disassemble the rear of this lens?

What do you mean by the diaphragm pin? The lever for stopping down the aperture? Why would you want to remove that?

He stands outside of the lens. I am afraid that it will damage the mirror.
