Just a couple of questions. Was it just going to be too much work to adapt the older cab to the newer frame to make it work verse the way you did it? Are the C30 frames similar in height and thickness as the ones from the newer square body? Also how do the 67-72 K20 frames compare to the same year C30 frames as far as frame height and thickness.

I ask because I know with the 73+ 30 series frames that are more stout than the 20 series. Just trying to put some things together in my head in case I get to do this to the 67 GMC C30. I have a line on an 85 K30 rolling chassis. I knew that it had been said that it probably would have been easier to use the 67-72 K20 frame but wondered if they were less stout than the 30 series frames either of the same vintage or the newer square frames.
