Manhattan Speed Parts '1968 Hemi Dart'

[Charlie A]

Does not really contribute anything to the topic but just wondering, were windshield wipers required in Super Stock and Modified Production?
Both cars have them.
And there is still a complete exhaust system hanging under the Camaro.
I remember the early Super Stockers were required to keep the exhaust and mufflers to the rear axle but Modified Production as well?
