Rear Tailgate Lifter Supports & Fuel Cap

I replaced the rear tailgate "shocks" on SoDak today. It took me all of 5 minutes and they were only $13.50 from FCP Groton. Now the liftgate stays up!!!! Instructions are Here. My wife lost the fuel cap and the cap is unavailabel from Volvo. Luckily FCP had one for $15. They were very fast on delivery as well. The fuel filler cap is Stant 10817 and it's made in the good old USA!
