Pete, a welding supply shop or likely any mechanical shop could crimp some good ring terminals onto a length of wire for you for cheap & I'd have em solder it too. EDIT as you know it will render the ammeter inaccurate. Just me I would keep it as is & clean ALL terminals/connections including ground paths & do Nachos' bulkhead bypass & one guy was adament on using a 30 amp plug in fuse, one of those colored plastic ones with the 2 male plug in lugs & to keep spares handy in the main line to the bulkhead from the battery. advantage is they would blow instantly if there is an issue & when when my '66 dart full fielded the FL didn't even do its job & go open & the wires were melted/shriveled from the excess amperage.
