Thanks Tim. I guess my first mistake was the model years in question. I should have said " Is the 1928 and 29 Model A coupe rear window panel the same as a 1928-29 Sedan rear window panel?"
That's the best answer I've heard to this point. Thanks. The only other difference I've noted is that some have the discharge at about a 45 degree angle, while others seem to shoot the juice almost straight down, on both #69 and 71 styles.
Excellent!! I just happen to have a NOS pair of these carbs, the other one is still in its original wax-sealed box. I was pondering some unusual induction for them....thanks for the ideas!!
