FN 142 Double - Middle Pan?

[ShadowIllusion]

I want to replace both pans with metal ones, the issue is, where can I find a metal pan with a similar layout as the plastic one in the middle? (The hole in the corner.) I am wondering if I have to costume cut out the hole for it or not..

Links to where I can find the normal pan, and possibly the one with the corner cut out of it would be appreciated!
