Re: Help-I Messed Up Fuse Block?
Takes a 1/4 inch standard (course) thread bolt.
If you heard a crack, then you broke the inner part of the fuse block. Yes, it is a type of captured nut. It has three spikes or fingers that dig into the plastic.
I don't believe the part is being reproduced. Lectric Limited will sell you a complete under dash harness kit for something like $432, but they refuse to sell parts, other than a few parts listed in their catalog. I believe they only have such parts for Corvettes.
The one in the pic I have attached is for sale, if I don't need it. I don't believe I need it, but won't know for sure until final assembly of my car. I have already pirated lots of wires, and other pieces from this harness, so it would be very difficult to make complete.
Are you in a big hurry? If so, it is possible to do an emergency fix. First, disconnect the battery!!!!
You will have to take out the two screws holding the outer fuse block to the firewall. Take the two halves of the fuse block apart (only two clips). That will expose the nut that used to be imbedded in plastic and is now spinning. You should be able to get some vise grips on it and remove your errant bolt.
You can either epoxy things back together (if things aren't too damaged) or you can use a nut and washer. Make sure the washer isn't in contact with any wiring. If you go the epoxy route, use something very strong, such as PC-7 available at most hardware stores. Needs to set 24 hours minimum.
If using a nut and washer, then you will need to attach your engine and front end harnesses BEFORE you put the two halves of the fuse block back together, so that you can hold the inner nut. That also means you cannot take them back out without disassemling the fuse block.
Really sucks breaking 44 year old plastic.
