94 Civic EX

Well I wanted to clear out my front corner lenses and found out that its not gonna be as cut and dry as I thought. I planned to seperate the lense from the back and take off the yellow plastic inside. Then I planned on resealing it. Well it looks like the yellow is actually a piece OF the lense that if I take it out will leave a whole in the lense.

Any good info or sites on clearing out front corner lenses?

Thanks
