....It's a bit of a generic chassis, but the McKinney and the Pluger chassis and most others are pretty much the same. There was a 3 bar chassis that some teams were experimenting with. I've not been to a drag race in years so I have no idea what they are using today. Monogram put it under virtually everything, the McEwen 57, the Prudhomme Firebirds, the Bernstein Tempo, the Meyer Mustang it works for just about everything post 77 or abouts.
