ok had some issues with the neg battery terminal so I went ad re-wired the bat, new positive to starter and underhood fuse, new grounds, and a few others that were just looking flaky. somehow I missed the main from the alternator to the underhood fusebox. does anyone know how long this is (and gage) so while I am out and about on lunch I can pick one up and not have to risk eye-balling and trying to find a ride back three towns over the weekend?

thanks for the help
