There were lots of darts with the 318/904/8 3/4 combo, its actually pretty common. Not rare at all in my experience

Especially in 1972! I check every junk 72 that I see. It was the last year for 8 3/4 in an A-body and I've found them under /6 - 904 four door cars. They were just getting rid of stock before they changed to 8 1/4in 73.
