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..

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
