I have a new set of Kolbenschmidt pistons for the 250SL engine.
Those are 1st bore, size 82.5mm. I initially got them for the 230SL. (The box was mislabeled)
The compression top is quite different between the two versions ( due to different stroke) so I had no choice but to get another set. I don’t see myself getting a 250 car anytime soon so my first set of pistons is for sale now. I’ll be happy if I can recover some of the money and put it back towards the project.
How about 950U$ shipped in North America.
