I was about to order some Bilstein Touring shocks for my 1992 535i off of ebay, but now I'm concerned if they'll fit. The seller's description reads:

"to fit 1988 to 1995 BMW E34 , 525i(except 24 valve) , 530i , 535i and 540i , 2.5" dust cap with 19mm nut , except air-leveling system"

How do I know if these are correct. The nut on top of my shock (accessable in engine bay) is larger than 19mm. Is this the nut being referred to?

Again it's a '92 535i no self levelling.

Thanks
