I was wondering if a 1947-1954 chevy pickup body would easily be installed on a 1966 chevy pickup chassis.......I am expecting minor mods like the relocation of the cab mounts and radiator mounts, etc, but before I sink the money into the project I would like to know if anyone has done this or could send me a drawing/picture from a 1947-1954 chevy truck manual of the frame or the drawing from an S10 chassis with dimensions......

That is not a swap worth doing. What is wrong with your original truck frame?

Some people march to a different drummer. I like to polka.

actually the problem lies within the original 66 body and sheetmetal..... The 1966 frame and chassis that I have is virtually perfect with the exception of the rear trailing arms that have already been replaced. So the chassis is in great shape from the 1966. There is hardly anything worth salvaging and I was just wondering if it would be an easy conversion from the 66 body to something else because of the availability of parts for the earlier years.

Although this does not answer your question, it does provide a lot of information that relates to the problem. Look at all the pages to this site and note the different shape of the frames. I think trucks and suburban or panel frames are very similiar.

As was said here if you have a good frame keep it and build from there . The 66 frame is a bunch of work and a tad bit to wide in the front. You really wont gain anything. I have built quit a few of this series truck and even keep one for a shop truck/everday driver. You can do a lot with it. The s-10 craze is just that. If you have no floors and want to build a complete truck i guess the s-10 is the way to go.(dave could step in here as i think he is the only one around that i have seen finish a car with one) But its not something easy and cheap as some peole would have you think. For every s-10 swap i have seen that even came close to be driven i have seen a dozen that will never see the road because there is a lot to it. Its not bolt on. What will you be doing with the truck? Does it have good floors now or? In closing u might want to find a little more tech board for this.The 3/4 ton frame is a very good start if you have one.

In just two days, tomorrow will be yesterday.

Have to agree that the stock frame is the way to go even if it needs repair. Up-date the suspension and repair what has to be repaired. You'll be LOTS of labor ahead.

If it don't drag every now and then, chances are that it is not low enough.
