When I bought my 68 it had a battery drain that the PO apparently didn't feel like tracing, so he just put giant alligator clips on the ends of the battery cables.
It also had different cylinder heads on it. One was a 307 head and the other a 283 power pack. Also, when one of the "10" badges wouldn't stay on the fender, he ran sheet metal screws through the "1" and the "0" to keep it in place. My dad always told me growing up that if you do something half-a$$ed, you'll have to do it twice.
