HI ,I am looking to replace my alterntor.I would like to Know if any body has a suggestions . what about install a GM alternor?

No quite sure why you would want to go with a different alternator. but in the process look at the Amerisport/Kirk Evans hump reducing kit as it has a relocates the alternator to give more passenger side seat play.

Why replace. Rebuild the Ford. Cost me $30. at a very reliable rebuld shop in san diego. has run for years.

If your car is completely stock, the Ford 60 Amp alternator should be fine for your application. You can probably get one at your local autoparts store.
If you've added additional load on your system with hi-flo fans, hifi stereos with power amps, super-bright headlights, et cetera, you may want to consider getting a 100A or greater output alternator. It also allows a faster recharge for your battery, especially during night drives when there your alternator is working the hardest.
Be aware though that if you do consider a hi-amp alternator, you may need to upgrade the charge wire accordingly as your stock 'Lucas' wire may not be able to handle the increased load. View the manufacturer website for assistance in choosing the correct gage wire for your application. My 100A alternator upgrade did not require upgrading the charge wire.

Good luck

Another consideration is that most late model alternators- of any output power- use an built in internal voltage regulator, causing confusion when adapting it to our cars with the stock external voltage regulator. There's a lot of info on the web about this change, mostly wrong. Good luck- J DeRyke

I install a mustang alternator a cople of years a go with an external regulator . The Amp meter jump around a lot so I purchased a new reglator from pantera preformance . Now the meter only jumps a little. I was having a proble with the battery go dead so I brought car in to auto zone. They checked it out and said the alternator was charging off and on . They said I should replace alternator. I don't know how many amp it is . I did look up info on the web may be the mustang alternter should be wired differantly ??
