'60-'66 Body On A '73-'87 Frame

[Captainfab]

Yes, that could be done to lower the stance, just more work to do get just a stock C10 ride height. On the above truck, using the '74 frame was not my decision. I was wanting to locate a '63-'72 frame. And I do understand that in some parts of the country, good older frames just can not be found

Not saying it's a better alternative than an older frame (I'm with you - I think it sits too high), but sometimes the opportunity of a good frame doesn't always present itself.

The '73-'87 frames drop down a little lower under the cab than the '63-'72's, and then they kick up too far forward for the older cab to sit down where it needs to be. The frame behind the cab has a different contour than the '63-'72 frames also.
