Somewhere on the Net, I found that Monroe 5979 would fit. Couldn't find them. I called Monroe and they told me that they were out of production and that they made no compatible shock. I gave up on Volvo V90 and searched Monroe 5979. I found them from a internet supplier, who was down to two, so I took them. I found other suppliers at more money, most say they have two left. Amazon lists them, as does Walmart. eBay also has several for sale. Good luck.
