new gauges for a 350??

alright.. so i have a 93 isuzu, and a 350 to drop in.. but i am having some truoble figuring out how or what gauges to run.. can anyone help me out?

alright so i found some.. but what is the difference in a mechanical and electric speedometer?

mechanical you have a cable running to the gauage and i believe the electrical is just a wire, i know i had mechanical on my ranger and there was a cable, i'm gonna switch it over to electric when i put it back together i think though
