ok i looked everywere and it seemed so hard to do a alternator swap in my datsun iv got a 69 510 4dr with a L20b outa a 76 620 pickup
after seeing some pretty crazy swap setups and custome brkates i whent down and bought a GM single wire alternator drilled out the tapped hole on it and it bolted right up to the stock mount on the engine used 1 washer to space it so the belt was straiter, and hooked up the one wire and havent had a problem with it after daily driving it for 2 weeks now. just though id let people know how easy it really is.
