Back in the day, a number of Waterford cars ran the bent-down trunk. They were sometimes referred to as Waterford Bob-tails. A couple examples are the Bunnells 318 from '67. the blue M-car driven by Bill Scrivener n '67, and the '66 champion 716 driven by Charlie Webster.
As a historical note, Stan "Stash" Majiewski (spelling?) builder of the L&M and M, lived in Westbrook next to his brother-in-law, Fred Beaber, builder and owner of the 716's. Both were very good builders as history shows.
