'Match Race' ~ 1968 Barracuda '340-S' vs. 1971 'Duster 340'

I am curious if there is a difference in weight over the real wheels on these two cars?

From what I've read, the weight of the rear glass in the barracuda over the rear axle put it at an advantage compared to other models.
That being said, I'm not sure how it would compare to a duster in particular.
I really wish I had been around when these cars came out. I was born a generation or two too late lol.
