Fusible link upgrade possible?
Cheez, it's not like throwing a spare battery in your trunk box. Buy two or three different brands (if you're paranoid about one being crap), install a new one, toss the rest (including the old one if its' still good) in the toolbox with two sealing crimp connectors (Don't know/have the sealing kind? GET SOME) and a lighter, and move on with life.
If the fusable link pops while you're on some road trip, you got bigger problems anyway and stabbing a new one in isn't going to keep you from getting your travels ****-blocked a mile down the road anyway.
