Battery door replacement

[Peaselbeast]

Hello all!
Just been working on a 1978 American clipper I purchased back in Feb 2021. She is missing the external batter door on the side and it is exposed to the elements    see attached picture for location.
Anyone have an extra or know of any place to find one? Otherwise I am thinking I will have to patch it closed before the winter.
Thanks ^_^

Hello and Welcome,

I Would Try Allied Trailer Supply, Or All-Rite.com
They Should Have What You Need.

Good Luck,
Clipper Joe
