I swaped a 130 alt out of a newer mustang for my 65, all I had to buy was the wiring kit from that same company you where looking at and I had to make a bracket for the alt to mount up. but now that I think about it, it looks as though a taurus (sp?) alt might fit with less work, I found my alt on ebay for about $60. plus like $30 for the wiring and like $8 for the sheet steel I used for my bracket so for $98 I think I did ok, oh ya I had to use the pully off of my old alt.
