It's a shame the cover has a hole in it and the grating on the top is broken. You would need to source another cover for a full restoration.
I would just fix what needs fixing and use it as is.
I have a green thumb latch catcher from my side pull full crank Mustang I could use for this.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
