Wagons were super competitive in Modified Production, Stock and Jr. Stock classes where Weight/CID was used. Gassers not so much. See above Posts 17 and 33
Poked around online and found these, not all gassers , some odd ones , some wannabes...but they are wagons and sedan deliverys .
Found a few more ...again not all gassers but I did find one early "Wheel Standing Wagon"...not a "gasser", maybe a "asser" Sorry ...moving on.
You got that right Denny, that car was so clean ,simple and to the point=very cool. I still have this unmolested copy of the magazine.
