It never happens when it's on the lift in a nice clean garage does it?
There are a lot of places to buy the cable and crimps, even Ebay. I don't recommend the hammer on crimps I much prefer the compression crimps. Of course you have to buy a crimper for them. They're rated for the full working load of the cable. Also don't buy 7x19 cable buy 7x7 it's much easier to work with and you don't have those tiny strands of cable poking into your fingers.
