Have had a real wrestling match trying to get front struts replaced on my 1994 Deville. They are electronically controlled, tied to the onboard computer. Dealer items, ordered by VIN, did not tie in correctly. My mechanic and friend ordered an aftermarket set, not self-leveling and not connected to the computer. But getting info, parts, etc., has eaten up a couple of weeks. Anybody with experience about these struts?
