"NB Max Caster design requires removal of some metal around strut top. If you prefer not to modify we can supply a top mount which is a straight fit however caster will remain standard (on the dropdown menu)"
the rod on a normal style damper is two small for the bearing hole i think. the gaz rod is very large. I also think think the bearing life of solid style topmounts is suspect on a road car but thats another topic.
