I am planning on relocating the battery to the frame on my 64 to un clutter the engine compartment. I had thought about the connection issues and didnt want to end up welding my wrench to the frame taking the cables off , so i am going to use these
http://www.hgmliftparts.com/default.asp?ID=30 they handle the load of electric forklifts that are driven all day with no problems. I got a couple from a mechanic at work along with enough welding cable to run my power / ground. I was even thinking of putting a connector on one end of a set of jumper cables so i could just plug them into my battery and have the clamps on the other end.
