Hallo Christian,
I was using rubbers that came with car, when ET bought it !
They where perfect, I did not use glue or something because they fitted perfect !
There must be some left overs somewhere, If I find them I'll ask if they can reproduce them ! I'll let you know !
I'm also plannig to make the rubbers between the alu frame and the top , I just need to find 5 cm from a original rubber ! If there is hebmuller owner who's 100% sure his old rubbers are original and could sent me a sample, Then I could have new rubbers in 3 weeks Max !
Best regards,
Guido
