part number?

[Cloggy Saint]

Why is there no part number for the rubber shock boot thingy, #13?

Does anyone have it?

Only cars with factory fitted Bilstein dampers use that boot.

And the rest, no boot ?

Yes, just 11 and 12 which are NOT used on the Bilstein equipped car.

I've just got a set of Bilstein B4 shocks, so do I need this boot and to ditch 11 & 12? And if so where can I get the part #?

[pacerpete]

B4s have an identical shaft / rod to the standard Boge / Sachs dampers so they utilise 11 and 12.
The only factory fitted Bilstein dampers were the B6 / B8 which have a much thicker damper rod and an internal bump stop so 11 and 12 cannot be used.

Ok, thanks.
