1977 Cale Yarborough / Junior Johnson Olds is getting worked on. I wonder what the situation is, collector just wants to keep it running, or takes it on the track for fun?

just exactly how many people had to ignore this car's obvious differences from stock, for it to race, and not be used as an example of what's not allowed in stock car racing?

or was there a plus or minus from factory angles on the front and back, and an allowable amount of chop to the roof? 

the top was chopped three inches and the windshield laid back 20 degrees. 

Junior Johnson's flying banana is what I believe it was nicknamed
