The stupidest thing I have ever done...

I'm glad I'm not the only one, twenty five years ago I raced my Plymouth fairly intensely, I broke a ring and pinion on Saturday so I loaded up and went to my shop to set up a new gear set and build a 727, I had the all parts needed and enough time for a good thrash. Well about 3 am we all went home with the transmission, driveshaft and rear gears bolted in thinking that we'd come in and finish up the small stuff and go back to the strip. So I come in in the morning and the first thing I notice is the converter on the bench. Duh
