Mine were $20 from Steeda. But if you get that uber-kickass one from Focus Sport, I think its in the range of $100 (V-F or something like that). But it is a completely new mount, not just the inserts. The hardest part of the install is getting the old inserts out of the mount. I would suggest a large vise. Put two sockets on the metal of the mount on one side and one the other side, put a long socket in the middle out the rubber. Screw the vise together and it'll push the old insert right out - thanks Tek!
