[urq] Hood lifter mods ...

[urq]

I saw that Blau had a conversion kit to add pressurized struts to the urq
hood so I ordered it ... before I go and drill the 4 holes for it I thought
I'd see if any others here have used this kit, or is it better to get the
factory parts?  By any chance does anyone know if the gas cylinders Blau
uses are standard cylinders?  I don't see any markings on them, so I want to
make sure that they are readily available.  From what I've seen of Audi hood
struts they don't seem to use the ball and socket joints for attaching.  

Thanks!
