Lombard inflatable floor board joiners

[Tertle]

Hey team,

i think that are called H-Joints or similar, ive a Lombard 4meter inflatable that i am slowly fixing up, got the leaks sorted, fixed the outboard, sanded down and repainted the floorboards with marine primer and paint, the only thing i need are the joiners between the floor boards. Not sure if anyone has any idea where i could find some to replace the buggered ones or old ones lying about?
