Thats a nice setup he has. Just be aware that the brackets in that ad are for a short waterpump setup. The brackets are different for the 69-up LWP configuration. Also, if you have AC and the alternator is on the drivers side, I don't know if that pump will work. 67 and 68 with SWP used a remote reservoir. I think that filler will hit the Alt. No AC, Alt on pass side shouldn't be an issue.
