I have an a/c car and I took the a/c compressor off along with the bracket. I kept throwing belts off alternator so I put the bracket that held the a/c compressor back on to brace the alternator. What does the bracket look like on a non a/c car and can I use one on my car? I have a 1970 gs-455. I'd like to see a pic off the bracket used on a non a/c car.
It is Aluminum and triangle shaped. It will work on your car and upper brace is the same for Ac/Non AC. You can find them on any non AC 350 car as well but pretty scarce now. if you are throwing belts I doubt it was the AC Bracket. It is probably a rebuilt alternator with an ovaled out lower bolt hole that prevents alternator from staying straight. I don't know why rebuild comanies do this? Good original alternator holes are round. Also could be mismatched pulleys from different years.
As stated above, check your pulley alignment. Make shure the alt. is tight in the bracket (not moving around). Check the alt. adjuster bracket (the top one with the slot) for crack in the slot area. And check for propper tension on the belt, about 1/2-3/4 inch pushing on the long side is good. If all this is good you may need to get a deep groove pulley from Summit.
Thanks for the replies. I'll try to find a bracket here on the forums and elsewhere. Without the a/c compressor bracket on my motor you can literally push the top of the alternator back towards the motor even if you tighten the upper adjusting bracket and the lower bolt. The alternator is very unstable without the compressor bracket but it is so large. I'll also look at the bolt hole and make sure it is round but i'm sure the belt slipped because of the missing top bracket ( compressor bracket).
Hey Dave, In looking at the pics you showed if I use a bracket for a non a/c car, does this eliminate the top bracket? The top bracket I have ( compressor) is very large and I thought the non- a/c would have a smaller top bracket if any. I can see from the pics that the lower bracket is different that what I have. Will this lower bracket be stronger and eliminate the need for the top bracket that mounts from the alternator adjusting bracket to the intake bolt?
You do not need the top bracket if you are not running the AC compressor. Do NOT run the car without a lower bracket of some type and the thin adjustment arm. This is your problem! Do you have the arm with an adjustment slot that attaches to the water pump and goes to the top of the alternator? Show a picture of your set-up if you can. Sounds all wrong.o No:
Here are the pics of my set-up. I'm hoping that if I get a non-a/c lower bracket than I won't need the upper bracket shown in my pics.
That is correct. You will not need the upper A/C bracket when going to the non A/C alt. bracket. A/C and non A/C use the same alt. adjuster bracket.
David, I have the lower triangle shaped aluminum bracket that you need. I need the upper and lower brackets that you have. Lets work out a trade. Please email me direct at cacmanjr@aol.com or send me a pm on this board.
Dave, what is the nut for on the upper alt arm? IS hole stripped? Alt should be threaded. I can tell rebuilt alt because of stickers so I bet lower hole is ovaled out making geometry a bit off.

The nut on the alt. arm? One is bolted to the alt and the other is bolted to the upper compressor bracket. I haven't looked yet but I think the bottom alt hole is Ok.
should not be a nut on bolt going through the upper arm into top hole on alternator. Hole is threaded. Bolt too long as well.
Hey I put a non a/c bracket on the alternator and it doesn't move at all. Fixed my prob. Thanks to cacmanjr.
Hey there, if you do go with the non A/C bracket set up, I have a pal who would love to have that AC Alt bracket; is it available?
