Power brake booster size - The 1947 - Present Chevrolet & GMC Truck Message Board Network

While at the local bone yard, I came across a 69/70 C30 dumptruck and noticed it has a smaller than usual power brake booster. (first I've seen)

We're there different sized boosters or was this just added from some other vehicle? (didn't look added to me though)

3/4 and 1 ton had dual diapragm boosters which are smaller in diameter and slightly longer.
