pretty sure those mounts come with the factory hardlid. mates got the same ones on his ba mkII. from what I've seen they aren't very good. bending and vibrating. my aftermarket hartop just has simple gas strut end that is screwed into the plastic tub, which I haven't tryed but I'm sure I could move closer to the cab for more lift.(but then my mrs wouldn't be able to reach it to close it.lol)
