Tom; Thanks for the response. My old shocks are Stabilus Lift o Mat 752991 0600N 017/05 A5 and 22 inches fully expanded. I googled Stabilus and for the life of me can't get anything usable. Don't know if Stabilus is out of business or a foreign company. Took old shock to a number of auto parts stores and no one knew how to read the part number as to how many pounds of lift. Also, found 22" is an unusual size. Even took the old shock to Quartzite, with hopes I could find a match, but no luck. At NAPA, they felt they were 75 lbs, as the number started with 75. Put the new 75 lbs shocks on and the door immediately closed and was extremely heavy, so obviously way to light. They will special order a heavier shock, but I had hoped to determine the correct strength before I special order. Allied, although they have the shock in stock would not provide me with any info such as manufacturer or strength weight. Obviously, knew I planned to price shop. Haven't given up, but I hope someone on this forum has already solved the problem.
