Questions: I bought this MC and need to change the rear fitting to the original banjo fitting for brake line clearance. Do you have the crush washers ? Thanks
Question By: Dan Butcher on Jan 14 2018 1:46 PM
Sorry, i dont have a good listing for those. Napa should be able to get you the crush washers you need if you give them the ID and OD you want.
