I ment to add....
You can find them on Amazon, just punch in 20 inch, 20 lbs strut, and it will bring them up.
Save the ends from your old strut as the new strut may come with a bigger (in diameter) end. Found out, at least on my Lexi, that a larger diameter end will not clear the door when you close it. The new ends will fit on the "ball", but when you close the door, it may bind because of the larger "end"
Just transfer your old ones, they just unscrew.
Or, you can do what I did. Also from Amazon, pack of 4, GSB 10mm Ball Socket End Connectors.
Their metal, not plastic, are small and very strong.
