Pentax ME Super Fresnel Lens......

Can you change the Fresnel lens on a Pentax Me Super
Slr Camera. I repaired the lockup mirror problem
that you have with these bodies by carefully removing
the aged foam and cleaning where the foam tape was.
Spent hours doing that. All went well, carefully
cleaned up everything, was very careful with the mirror.

Lastly I noticed looking through the viewfinder that there
was a small piece of dirt on the Fresnel lens. I tried to
carefully clean it off with a Q-tip, the dirt came off
but I noticed that there was a smudge now in that area
and I took another Q-tip with some rubbing alcohol and
tried to clean the lens.
Cleaning made it worse and worse to the point now where
the lens must be changed. Has anybody changed a Fresnel
lens on this camera.
There seems to be a screw that possibly holds the Fresnel lens
retainer plate and I was wondering if you remove it
is this how you change the lens?

Your assistance appreciated
Denny B
