Difference in cab mount bushings.

Im not 100 percent sure on this, but I think 3/4 ton and 4x4 cab mount bushings are the same. While the basic 2 wheel drive 1/2 ton cab mount bushings are different.

If so why would a cab mount be any different on any style of the 67-72's? Are the frames that much different on say a 2 wheel drive 1/2 vs the same truck in 3/4 ton?

I feel like Ive read that the thickness of the metal was a bit thicker on 3/4 tons, but in my mind I always figured the outside diameter would be the same but the inside would be different on the 3/4 tons.
