Does the OEM rear damper bushings fit on the BC shaft (without using the metal sleeve bushing)? Do the BC-supplied nuts have the correct thread pitch and diameter for their damper or are you supposed to reuse the OEM nuts and washers? Given that you have a non-EDC setup it looks like things might fit. If they can't give you the support needed to install the dampers then what happens if something major goes wrong....sorry for the install problems
