1969 Camaro Battery Tray

[68camaroz28]

This has been on interesting journey so far as I was one who contacted Steve along with some other Camaro friends trying to understand what was wrong with the battery tray I had in our 68 Z/28 restoration. I thought I had checked it out and had a NOS GM service replacement but the judge at MCACN told me and deducted a point for just that "service replacement." The judge who did a very good job found this by feel. Later that judge came back to look at our car and was complimentary and he tried to show me what he was feeling for but I was feeling in the wrong place and missed what he was trying to convey which was all my fault (dang hearing ain't what it used to be). I just thought no big deal and will check it out when I get home. Well, that is when I was shooting blanks as I could not see by comparing battery trays what was wrong until I contacted Steve and others for help and assistance. I have pictures and information on our restoration build over at Team Camaro but here is what I've put together so far concerning the tab. It's interesting that I have not seen a NOS service replacement and a few have been very old ones with that tab where the clamp bolts on. Another point brought out by a friend which I had started to note was the nuts on born with battery trays seems to always be angled whereas GM service replacements seem to be always straight.
