Hey all, got a couple questions on my 78 Flatbed.

First off, does anybody have a similar truck and can take a picture of the fuse cover? Searched google but all I could find were covers for FJ's. My cover is long gone and have no idea what fuse is which. To make matters worse the PO replaced most of my fuses with 30a fuses. I had some troubles with the radio over the weekend but was able to fix it by fiddling with the fuses, so I am planning on going through all and cleaning up the connections and putting new fuses in.

Second questions, my brakes sqeual in reverse. Going forward everything is fine, good pedal, stops good, no noise, but as soon as you back up it squeals. Its not a little squeak either, its an ear-piercing squeal. Doesn't seem to matter if I'm backing 2mph out of a parking spot or 10mph down a hill, squeals the same. It seems to get a little better after the truck is driven, but its still there no doubt. Any ideas?

 

Here is the fuse cover from my 79 pickup, hope it helps...

 

Thanks Vitod. Unfortunately the 78 uses glass fuses all in a line. Guess I'll have to do it the old fashioned way (pull each fuse one by one and see what turns off)
