datzenmike Posted July 29, 2008 Report Share Posted July 29, 2008 As long as the distance between the brake and clutch m/c s are the same, you should be able to run the 620 booster and dual m/c in your 521. Preferably get one from a pre '78 as they have front disc brakes and the return valve is set for a different pressure. (lighter I think). I think they are removable, so I guess if you only have a '78 or '79, you could have a rear one installed in the front outlet. Quote Link to comment
