I'm trying to put together a pair of Bosch Euro Smiley low beams I was able to source separately last year and I know what I need to order for the screws/adjusters, etc.. However one part I still need is the gasket ring. They sell the HELLA version online but the BOSCH part number doesn't show up anywhere. I am wondering if anyone know if the size is the same or if they are completely different. I cannot find any specs on either so I'm wondering if I should take the chance and order the HELLA part. Any info would help. Thanks
