Rear light gaskets?

[MerlynIIa]

Hello. I have a set of rear lights from my '65 IIA parts Landie (the big red kind) that I want to use for my rebuild. the housings are nice and the lenses are good, but the two gaskets on each are shot. they need the one behind the lens and the one between the unit and body. Some type of soft rubber neoprene type material. I assume I could make some, but does anyone sell the replacement gaskets so you don't have to make your own?

Thanks!
