The parts now sold by shop4parts now come like the above - it's clear that you have to push the end of the bump stop into the rubber boot, but I can't find any way to do so. Brute force, heat, soap, even took it to a garage who couldn't work it out. Has anyone found a way to assemble them? This is how the Original Birth ones come as a fair warning, car has been up on a couple of jacks and an axle stand for a whole week now due to this.
