I have all i needed to get the big 3 done but the only thing i cant seem to find is some kind of wire terminal end to fit inside the alternator bolt housing. I'm using 1ga wire and i every single ring terminal i bought from ebay doesnt fit in that housing.

Also, i noticed to factory wires going into the positive battery terminal, how did you guys get that connected. Can i just cut those off put ring terminals on those and bolt it on? Does anyone know exactly what guage wires are those?

I was in the diy big 3 thread but they were not very specific on those parts.
Much help is needed please.
Thanks
