perhaps you can just buy a new distro block? the knukonceptz 2 way one is like 15 bucks and its pretty versatile. and you can choose two fuses to come with it.
havent blew my 100 amp fuse on mine, and i push the crap out of it.I hear those 1000/1 draw far more than 100 amps, its time to get 1/0 and 250 amp fuses..
