Customer support ignored my question completely, so I just had to take a chance that the 32mm seals would fit. Turns out they worked, so that made me happy. Didn't appreciate the anxiety. I would order from you guys ALL THE TIME if you could confirm fitment on old Ducati Brembo master cylinders. Why don't you do that? I think you know how sketchy the availability is on old Brembo stuff and you guys could come through like champs if you could only add details to the listings or confirm fitment for your customers. Price on what I ordered was very reasonable.
