Tsunami/Sceptre 23' cabin hardware needed

[abl1111]

My 1975 Tsunami needs new interior cabin storage covers. They're made of laminated plywood. Actually, only the pair of covers with hinges are shot, but to have them all match, I want to replace the set.

My question: The pair of lami/plywood covers that have hinges on them, the ones that cover the step down into the cabin, have a pc of aluminum moulding that cover the front edge of the plywood. Looks like 'they' made a narrow cut with a table saw on this edge so this "T" like pc of aluminum moulding would slide onto place and protect the leading edge of plywood from all the abuse it takes. Great idea.

Where can I find a pc of aluminum like this ?

Thanks.
