[Dan-ny-m398]

I have a 1989 535i production date 4/89 I'm getting a set of bilsteins and I need to know if my car has a 19mm nut or a 22mm nut.

It's probably a 19mm, but you have to check.

Pop off the top strut dust cover and find out.

Here's a picture:

yep more likly the smaller 19mm. These can be changed to the 22 with upper strut mount replacing i think.

Yep. Probably 19mm - go put a socket on the nut and see what fits.

If you're planning on replacing the upper strut bearings anyways (and you probably don't have to) - to my knowledge the 22mm versions fit. Might as well go with the slightly beefier design.
