replacement fuse block

Be careful with some of that aftermarket stuff.

Firstly, and it took me a LONG time to come around to this, the new type fuses are VASTLY superior to the old cartridge fuses. And I do mean vastly. The old clips and fuses suffered from corrosion problems at the clips, poor contact there, and could blow a fuse right there because of heat

Second, and I realize the photo in the post above is just an example, the old girls were horridly under fused

Last, when buying something aftermarket, and there were some pretty poor stuff out there, look carefully at "how it's built."

If the thing is riveted together through the plastic, and the plastic is "thermal" then a small amount of heat can cause electrical failure. If you examine the original Mopar fuse clips, they were all one piece. That is, you could cut the plastic away and dangle the thing in mid-air and it would still function electrically.
