You'll need a whole new aux shaft. You can try Ford, but it may have already been discontinued.
Aux shaft PN# E4FZ-6A739-A. The last one I bought (in '05) was just over 100 dollars.
I don't have the part number for the oil pump drive assembly. Try Ford first There is no aftermarket option available for them either. The gear should be the same as a typical 2.3 distributor so that may prove to be a solution to that problem. Those are readily available.
On the high end, Esslinger makes a billet shaft and a bronze distributor gear set for around 270 bucks.
On the low end, Find another 4 cyl stang or Ranger in a salvage yard and grab the parts you need.
