Wow! That's the sticker!, WRe. Really, now how to find it to buy. yes, it could be a 108 part, but all the markings say it is applicable to the SL (113) too. My cylinder head says 280SEL/SL on it and is - as far as I know - the original part. I own the car since 1982 and the was no major engine work done before I bought it.
