Center Console attachment

[Beaver]

The guy I bought my 18 from had replaced the screws that hold the center console down with non stainless screws that are narrow and now rusting. While it still seems solid, already a few of the heads have popped off and I don't want to find myself in rough seas with the console sliding around the deck. So... Any thoughts on the best way to re attach my CC?

Should I just move the CC forward a bit or backward a bit and re-screw with stainless? I thought about cutting a piece of HDPE to attach it to and then attach to the deck.

Thanks for any suggestions.
