1/2 VS 3/4 Frames... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Howdy All,

I attempted to use the search feature to answer this question but no luck.

Other then suspension is there any difference between the frames on these trucks?

While surfing another forum I saw some one take two frames that were the same, and use one to box the other. He used the same size frame though.

My pipe dream truck is 68 3/4 but finding two of those frame is next to impossible, specially in my part of the world (rust monster). I figure it would be easier to use a 1/2 to box the 3/4.

Any one able to give me some insight on this? Would it be just as easy to cut my own steel to box the 3/4?

Thanks in advance,

Scott

The only difference is the rear cab mounts sit lower requiring a bigger bushing. In other words,just use the 3/4t/4wd cab mounts.They are the same frames.

I figured it would be, which isn't a big deal. I just want the contours of the frame to match, as it seems much easier and seams bug me for some reason.
