Frame width is the same, frame height and metal gauge will change.
WOW!!!  You guys never cease to amaze me! Those are some really cool charts! That will help immensely! I can't thank you enough for that! 
As for the chassis I'm looking at, I'll have to go do some measuring. It looks like it had a flatbed of some sort on it, but appears to be short enough to be a standard 131" wb. There's no rear end under it currently, but the springs are still there, and the center bolt should give me what I'm after. I have a Dana 70 from a B300 motorhome that I am looking to narrow down and put in it, with disc brakes if I can. My 67 will be going onto this frame. The biggest decision I have to make is what power plant I'm going to run. I'm itching to build the 543" stroker from 440 Source, but a 408" from my LA 360 might be a better engine for a driver.
PS: You wouldn't happen to have this same kind of chart or info for the 66.5-71 Sweptline trucks, would you?
