I ordered a set of 126 321 17 04 based on the points system in the manual and the availability online. It seemed that where ever I punched in 420SEL the 17 04 spring came up.

I also installed the 4-nub coil spring shim based on the point system and indicated availability online.

I got these installed last night and the front end still seems to be sitting higher than it should.

Now, all the front end parts were removed and replaced so the location of the lower control arm's eccentric bolt might not be where it "should" be and the same as the guide rod. I am not sure how much these effect ride height on these cars.

Also the rear spring are 116 324 11 04 with the 3 nub coil spring shim. These numbers agree with the 32-240 PDF. So the rear springs are correct..
