Frame differences 2wd to 4wd - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm wondering if anyone can tell me the difference between a 2wd and 4wd frame in these trucks with regards to the main frame rails around the engine x-member / manifold area. I'm wondering if the rails in that area are the same dimensions or not?
thanks.

There are differences. They relate to 2wd vs 4wd as well as payload capacity (1/2, 3/4, 1 ton) and even longhorn.

For a better breakdown search at the top of the page. SSTim give a detail explanation with numbers etc...
Before hitting the search button remember to mark the 67-72 button.
