Seeking tail light cans for 50s trailer

[dkatvan]

Hi there! I'm restoring a 57 flying cloud and the light can and light mechanism are all rusted out.

I have the Bargman No 6 lens and the metal frame, just need the can and light mechanism.

Vintage Trailer Supply usually carries these, but they are currently out of stock: https://vintagetrailersupply.com/rou...t-can-vts-584/

Any idea on where I can find them or something comparable?

Thanks in advance!
