Quote from: Road Reptile on May 28, 2024, 09:06:14 PMHi again 67 fans,There are a multitude of cars out there without AC that have the bracket. There are also cars that have heavy duty battery but no bracket . Not all A/C cars have the bracket or a hole to suggest they ever did. Consequently it doesn't seem prudent to suggest that they are related. What you can say for sure is if the car had a hole in the apron or fender then that meant it had the bracket when it left the assemblyline. Any other assumptions are still only speculation at this point. If cracked batteries were a big issue there would be historical documentation like a TSB to correct that issue which there is not that I am aware of. It wouldn't hurt to modify your car if it made you feel better to have the bracket but given the multitude of cars that don't it doesn't appear essential to have it ether.Of course if there is a empty hole in the apron where the bracket should be then a bracket was there in the past and is now missing.I think NPD still carries a good reproduction of the bracket.
This small bracket seems to be on cars with A/C and as we know they also have a H.D.
Battery. This may have been added to eliminate the "shake" that occurs when the added load from the compressor attempts to slow the engine down. We also know that the A/C
belt tensioner was redesigned to prevent belt vibration. Seems most cars lack this small
bracket and really should have have one. Batteries are expensive and will crack with the
added vibration without "Z" bracket in place, acid damage is no fun to clean up. Seems that only cars built after Feb 67 have either option so the number of cars will likely be small
