If you really need those , I am giving away for free a set of 4 banjo bolt seals, that work with every banjo on BMW motorcycles, perhaps some other cars.
DO NOT purchase just these seals, because I will not ship them! If you get some other stuff/service and also these seals, the seals will be free.
The OEM part # is 07119963072 or 34327661818 .
(had to put them as 1 cent otherwise the webstore would not accept them. so they are not actually free, they are 1cent/4 pcs.)
