Just bought this ride, $250 a great deal except the wiring harness is fried, alternator is gone module is gone, all the wiring is melted into one single line. it is a mess to say the least.  I did salvage the wire to the heater, wiper motor, and head lights but that is it.  

where can I find a reasonalble wiring harness and an alternator with one wire.  I suppose I should say that the ole boy that had this before me has put in a 302 with a c-6.  I am not sure if it runs due to the wiring harness melt down.

also what type of rear end is in this year of truck?
Thanks  

Can anyone help out, thanks.
