Disassembly of Pentax FA 28/2.8 lens

Hello all,

I am trying to disassemble a Pentax FA 28/2.8 lens. It is in excellent condition and takes amazing photos. One issue that bothers me is the very tiny streaks of fungus on the front element.

I successfully retrieved the optical block from the lens housing however the front glass element seems to be impossible to be detached. I mean, I can rotate the front glass element on the block which means it is not glued but housed on the block. But even using soft scotch tape to hold it by its large surface area, I cannot pull it out.

Does anyone have an idea how I can remove it to clean it?

Attaching the photo to show the block.
