I've spent this morning swapping out my stock suspension, and wound up snapping off a few bolts, the LCA bolt, and one of the bolts on the strut top hat.
Obviously, the LCA bolt should be pretty easy, but the top hat not so much.
Every diagram I have looked at shows to different parts, the "base" and "base, front fork mounting". Does anyone know what the difference between these is?
Also, would it be possible to just have a new screw pressed in? All the local parts stores will take at least a week to get it in, and I am carless until I get this taken care of.
