Front shock part numbers?

[noid]

Does anyone know anything about part number 31 32 1 130 065?


I know most people replace with 31 32 1 135 892, but there must be something to the part number above.

Factory Bilstein shock (same as HD I think). It came in the M3 and 325iS if I'm not mistaken.

You guys put in that Meyle shock cartridge for me, do you remember what brand you pulled out (the blown one)? I can tell the one you guys didnt replace has a much thicker shaft, then the new one (maybe because its meyle?).

I am currently looking to replace all 4 shocks, so that they are all the same.

That car had ORIGINAL Bilsteins if I remember correctly.

Like... from 1987.

Was it a mono tube?
