Those 3 speeds in the Nova were notorious for locking up the shiftier linkage...
I had a '71 and a '79 Nova. The '71 was a 3-speed column-shift. I bound up the linkage once on a railroad crossing! It was one of those places where there are about a dozen tracks and after I'd passed the roughest of the tracks I tried shifting from 1 to 2 and got the thing stuck there mid-shift. It rolled to a stop there on the tracks and I popped the hood and had to reach down and fool around with the linkage until it "popped" back into place. A hectic couple of minutes there.
I had a 76 Nova Concourse a four door. It had a 350 4 bbl three speed auto set up as a cruiser with a 2:72 posi rear end. It was a great cruiser, but prone to "corrosion" (rust). I gave it to my father-in-law in '82 and he drove it for a few years until the corrosion became too bad to pass Maine state inspection.
It was my first custom built by Chevrolet car with all my special options.
Looking at the ads for the 76 Nova, mine new was less than $5300. I can't see spending $7600 or so for a 76 Nova six.
