Wingtip lights - metal plate/heatsink thickness?

[Flying Scotsman]

I inherited a Van's wingtip light kit and am installing it, but it doesn't have the two metal plates/heatsinks for the landing/taxi lights and the Big List doesn't show what they're made from. Can somebody tell me what thickness of aluminum sheet these dudes are?

TIA!
