Frame compatability - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My K10 72 frame might be bent.
What else will fit under the body? Do i need an exact year (or series) frame, or will a 73 and newer frame work just fine? And if I change frames, do i need also to change running gear? How late in model years can one go, before stuff starts not to fit? Maybe 80's? Even into the 90's? ideas?

The Square body frames can work.
There is a lot of modification involved.
They have a huge dip in the center of the frame.

Here is one old thread I found.

Collision repair body shops should be able to straighten the frame. Have you looked into frame straightening through a shop?

Also the 69 -72 Suburban 4x4 frames will work. There are a few mods to make but much less than the square body frames. There may be other years as 67 and 68, but I have no experience with them..
