e93 convertible lift support shock

[zbabar]

hello,
I have a 2007 335i convertible,
the lift support shock is leaking and im trying to replace it,
the new ones are very strong and will not compress by hand at all.
I have tried to open the top half way to fit but the length is too long for it to snap it perfectly.
OEM part # 54377128764

I have searched all over google and youtube and I have found no info or help on replacing the lift support shock.

thanks
zee
