Nuts......quick delivery......ordered wrong liftgate struts. They're too long. Now to wrestle with RockAuto for the RMA to return these.
Took a smart pill. Looked at the parts for brand & part numbers. Then began an internet search. Funny thing is RockAuto has a direct fit replacement, but the word description isn't correct. I had to chase the original part number thru Stabilus (part brand). Fortunately, I came across a direct replacement list with dimensions of the part.
These things have serious force. 755N roughly 165 lbs of push.
Oh well, my fault for ordering the wrong part. Lesson learned. Don't fully trust word descriptions.
