Hello all, I finally figured out that the master cylinder on my 1984 416 with dual circuit disc brakes is bad. I bought one off of ebay and it has banjo fittings on it between the master cylinder and the ports for the brake lines. I'm assuming I have to plug the banjo fittings because my 416 doesn't have them on the master cylinder, but I have no idea what size the fittings are. Has anyone on here used one of these type of master cylinders before? Does anyone know the size of the plugs I would need? I don't have anywhere I can take it to get the plugs, so I'll have to order them on line. The company I bought it from won't return my e-mails. Any help would be great. Thanks!
