Elmer,
The original you bought is fused with these all the spots on the board is where one of these attaches that is how they are protected fuses stick out horizontally from the board. This is Denny Graham's stuff that he reproduced.
Just thought someone might be interested in what the original fuse holders that are pictured in the radio installation manuals looked like. Made up drawings from an original someone was kind enough to loan me. Takes a day to make one but I think it would be hard to tell them from the original one that was in the kit. These take the AGC or SFE 14.
