Piston Ring set (18) for engine block number 130.980-12-047632

[SuperRobbieG]

I have a 1965 Mercedes 230SL Pagoda with a non-original engine block number 130.980-12-047632.  I believe it’s from a late 60’s/early 70’s 280SE (W108, W111) which had a 2.8L inline 6 cyl.  I am looking for the following:

•   1 ea. Piston Ring Set (3 rings for each piston)

Thanks for any assistance.
