The 251 829 331 A Strut is Standard Duty strength.  Originally for models
left & right that don't have a Rear Wiper Assembly (these are a bit
"weighty").  So if yer running a bike rack, I wouldn't use these 'cause it
won't stay up (personal experience)

The 251 829 331 B is the weakest one and is mounted on the LEFT side only.
This allows the Hatch to stay partially open when used with..

The 251 829 332 is the strong, heavy duty type, usually just mounted on the
RIGHT side so that the Hatch can be left partially open AND withstand the
weight of the Rear Wiper Assembly.  However, if yer gonna be running a bike
rack, I strongly recommend running this Left and Right.

I I've been using two "332s" for the past 10 years with really no problems
and it doesn't "fly up" on me that I've noticed, but then I've always held
the Hatch edge firmly when opening it up.  Closing it when I don't have the
bike rack attached is just a little tough, at least I don't think so
difficult given my upper body and arm strength has diminished since my open
heart 4 way 6 1/2 years ago and the daily heart meds.  Personally I love
'em.
