July built car I would have thought it would sport them but you know those GM vendors, anything was possible.
The resonators and mufflers where the first to rust out on these systems thus where condensation would accumulate. Maybe that was a good thing for your car?
I do have two nos sd exhaust systems including 74 date coded mufflers. I know of only one other system besides mine on this planet. Rare stuff indeed!

Brewster,
You have two sets and one other set exist, what are these worth?

Curious.

Thanks,
