Where d I get fuses for my 66 coupe[289-4v]?? 2.5, 7.5, 14, 20 amp IIRC......I'm pretty sure I went to pep boys and they had some fuses but they were a bit too long to fit in the fuse box...Help needed!!!! Thanks...P.S.- how difficult is it to replace the fuse box?? Mine is o.k. but a new one would give some peace of mind....
