Source for 188 LSD parts ?

[BMG]

What BMW calls the compression rings in the LSD on mine are rather chewed up looking. NLA from BMW now, so is there another source for these ?
Part number 33141206909 I believe for a 1990 E30 M3 . Anyone have a used set if no other supply ?
Thanks

You can get them through Porsche. You need 2.0mm ears. ZF makes porsche's LSD units and BMW's.
