Hi Jackie ,
No padding on the SE's, not for Challenger anyway. But Wally's car is a rare optioned 71 Challenger so his may have been different.
appearing with Plymouth's third-generation Barracuda for 1970 was a Dodge relative, the division's belated reply to the Ford Mustang, Chevy Camaro, and other ponycars. Fittingly named Challenger, it was offered with a Slant-Six as standard power, plus V-8 options of 318, 383, 440, and even the Hemi. Models comprised hardtop coupe and convertible in plain and sporty R/T trim. The hardtop could also be ordered as a Special Edition with padded vinyl roof and a smaller "formal" rear window. Priced attractively in the $3,000-$3,500 range and cataloging a broad list of options, Challenger sold very well its first year, but then tailed off rapidly. In 1970 sales, sixes outpaced V-8s, while hardtops outsold convertibles. Only about 10,000 SE coupes were built.
