Do you still need a shot of the rear alt. bracket ? Just removed one sat. to replace thermostat and housing . Waiting on new housing , is that an SD only bracket ?

takid455 · 02-02-2009, 10:55 PM

yes, I still need a picture of it. I have an idea of what it looks like , but want to verify. I do not think it is SD only. the parts books do not mention anything about SD, HO ect. I believe it has to do with alt size (amps). My book says the number should be 496663. not sure if this is the right one as several were offered.

I dont have a tensioner, but there is a boss with a bolt in it on the back side of my alt. it s is stamped 1100928 55A. is this even the correct at for a 74 SD non A/C? has quadraphonic sound via 8 track.....ooooooooohhh yeeaaaaaa.

I will try to get a pic tomorrow night and post . It is a 74 air car with power windows etc. so I guess it would have the big alt. By the way white with blue lettering no hood bird from factory (has one now ) and red int. with rear console , SD, M40 & 3.08 rear .

takid455, if it doesn't have AC, I don't think that alternator is correct.

superdutybob · 02-03-2009, 09:38 AM

The 55A alternator is correct for your car if it has A/C and does NOT have either power windows or electric rear defroster. If you have either of those with A/C you would have the 80A alternator which mounts differently.

The PN you show is correct for the 74 55A alternator. When was your car built? There is a new PN alternator that was used late in the production year. I believe the 55A version ends in 428

Yippee!

My GTO is sold. I'll be delivering it within the next six weeks, then buying a '74 SD T/A.

Larry Navarro · 02-03-2009, 10:23 AM

Good deal Lloyd!!
Welcome to "the club".

67 Lamnas · 02-03-2009, 10:46 AM

If anyone has a single 73-74 455 SD NOS head, please pm me......

Brewster · 02-03-2009, 10:51 AM

Congrats Lloyd, glad things are moving forward . Look forward in seeing those new wheels!

lumarkhood · 02-03-2009, 01:18 PM

Lloyd,

That is very good news. Best part is "word of mouth" got it done. Speaks volumes of the car itself.

Now, Gary can go shopping again!

Lloyd:

Congratulations!

Start working on your SD snob attitude. It will take at least six weeks to get it usable at a local car show or cruise. LOL

johnta1 · 02-03-2009, 03:24 PM

Congrats, Lloyd!

Now you can be faster than those HO guys.

A non-A/C car would have had a 37 amp alternator.

A non-A/C car with rear defrost or power windows would have a 55 amp alternator.

The bigger 80 amp alternator with the idler pulley came on A/C cars with rear defrost.

Lloyd-TX · 04:30 PM

Thanks for all the props, guys!

Bob, I believe that I'm already gettin' this SD snob attitude figured out, LOL!

The pully system for the 80 amp Generator is mounted to the engine block on the right side by 3 bolts for the bracket and the 2 more bolts for the slide tensioner. You can find the picture on page 6A-27 of the 74 Service manual. If you don't have it I can e-mail it to you or fax it. Send me a PM and I will send it right out.

I do not have a/c or p/w. I do have a ref def. my car was built 6/74. if this is not the 'correct' alt, what would be the 'correct' one and would it require a rear alt bracket?

thanks DB4767 for the pictures.
