I want to replace my original fuse block (50amp for horn circuit and 35 amp for everything else) with a bock that accepts the new ATO fuses. Any ideas where I can find one with dimensions to fit where the old one is located on a BN6? I see some on line that have slots for 6 fuses but they all appear to be too big to fit.
