i did the same project 3 weeks ago and perhaps i can offer some advice... first suggestion is to call genesee products 918-274-8000. they sell a wire harness for 20 bucks. you can easily do without it but the job is easier and looks tidy. they also can sell you a quality voltmeter for about 30 bucks.again not mission critical but nice. i suggest you use an internal regulated alt. i bought a cheap re-built from auto zone for 15 bucks and a core charge. ask them to cross reference a 1978 chevy pickup. genessee provides wire diagram hook ups and the wires have all neccesaary plugs and terminals. you can also get a diagram online but it requiores that you find a one way diode or use a lamp to prevent voltage flow back to the coil. (spend the 20 bucks with genessee it is very worth it even if you do not want the volt meter) i was able to re-bend my existing generator braket to fit but it isnt "exactly" lines up but close enough for my purposes. you can also make one from scratch if you wish. to redo the existing one all i used was a large crecent wrench and a vise,and a drill to enlarge the bolt hole. simple and took about an hour once i got it figured out. the last thing you will need is a top bracket that allows you to slide the alt in and out to adjust belt tension. here again you can make one from scratch or get a chez tacky chrome one from the auto parts store. this is for a chevy also (i think edlebrock makes it. it is located with the engine dress up stuff) this has to be cut and drilled then mounted on a stud on the front of the motor. i used an existing stud and it was a close fit with the throttle lever on the front of the motor but it works wonderfull. i do not have the facilities to weld/cut so if you do perhaps making your own brackets is easier but you can certainly do it with over the counter stuff and hand tools. good luck and if you would like me to send you a pic of mine send me an email to fastguns@txdirect.net as an aside the other poster mentioned a 12 volt gererator and regulator this will work just as well but as inexpensive as the internal regulator alternators are i believe them to be a better solution with less wiring and a less complicated setup overall. good luck to you and whichever direction you choose good luck from s.texas!
