I would certainly check the markings more than just the colour of the bump stops to positively identify what you have. I have no information about replacing the bump stops, other than the contact details for Suplex in the "Parts Sources" section of the Alternative Parts List, available at the top of this forum in the Owners Resource Section. Not sure how up to date that is but I will be interested in your findings about some new ones. My Suplex shocks are sat on the shelf, not the car, so not as urgent. They are worth sorting out if they are Suplex as they are much better than the later standard Spax.
