nothing is going to be a plug and play FIT... Your going to have to modify the mounting braket to get the pulley / belt to align and a tightening bracket... The most common  "1 wire" is the old DELCO 10SI that has been modified internal to work on 1 wire... here are a couple versions on AMAZON..



Like them all, but love the "B"s.

Get your generator rebuilt and you will be good to go. No rewiring or fabrication needed.

On ebay there is a seller that has the bracket you need to mount an alternator.Alternator is the way to go much better than a generator and alot less hassle and cost.

And the regulator can cost more than an alternator and don't work a lot of times too
