Rear End Rubber Replacement

[Harry]

I am replacing the rubber in the rear end of my 1966 230SL and had a couple of questions.  The spring hat comes in three thicknesses.  I can't  see where the ones I removed from the car indicate what size they are.  Any similar experience?

On mine I could read the raised part number on in the rubber.

Hello

If replacing then cut the ring at the thickest point and measure, perhaps need to ad 3-4mm to that figure
