I have seen some earlier posts about this subject ( 2009 ). The contact info was outdated and no longer useful.
Does anyone on here have a good contact to purchase a complete conversion, Alternator and lower bracket.

Re: generator to alternator swap
Many years ago I used a GM 3 wire alt for the conversion. Used the original generator mounting bracket with a spacer, fit perfectly. Then there were no "kits" or ways to make the GEN light in the dash function properly using a one wire alt. I've had no problems for decades. With an internally regulated alternator, I was able to eliminate the rats nest of wiring and voltage regulator on the passenger side inner fender, to really clean up the area. Many different styles of Ford or GM alternators will work perfectly. Use what you think is best.

PLEASE invest a few bucks and buy all the shop manuals for your car. Definitely will save you much time and be an education.

Re: generator to alternator swap
Hi, I agree with Joe. I did the same as he did. I ordered a 72 Chev Nova Alt. Ya gotta spin it or clock it. (no big deal google it) That puts the plug facing you. I ordered PT2288 alt. plug and connected it so I had the gen. light. As long as your not trying to do this on the side of the road it goes pretty smooth. Take your time and ask when not sure.

Re: generator to alternator swap
I believe got my info from yblockforever.com . I don't know how I found it, I just came upon it. It was step by step , and they had the part number to the alternator that was needed for the swap.

CASCO (and I assume the other TBird parts people) have conversion kits.

Also look into the POWERMASTER PowerGEN alternators. They build a 12v high output 90A alternator in a package that looks like OEM generators, and they bolt up like originals.
Their website is : www.powermastermotorsports.com
If you click on the catalog tab, on Page 61 they show a direct bolt in, 90amp, unit for '55 to 63 TBirds. They also show 6V units for the '55-56.
I use one on the Y-Block I have in my '54 F-100. Works a treat and looks original. Needed it for the added load of an after market A/C. I left the regulator in place and dummied the wires so it looks like it still has the original charging system.
Cheers, Jeff

Re: generator to alternator swap
Thanks, Jeff. I've been considering using the Powermaster alternator, but had reservations, due to their 140 amp, one-wire alternator having a short life. It was installed on my Mustang 5.0.
Speaking of retaining the voltage regulator, I had the instructions for that but somehow deleted them. I would appreciate a pm with instructions and photo, if possible, at your convenience.

I don't like to put anything that isn't stock on my cars that I can't get through a parts store.

Re: generator to alternator swap
If you can get an original, rebuilt generator from your local parts store, I would pass; the quality of the rebuild would be questionable. If you insist on using the OEM generator, find a shop that has a reputation for doing quality work that backs its products.
