Chassis's don't interchange. If your chassis isn't a 4WD chassis, you're going to need one for your '72. In '73, the front axle was placed forward about an inch and a half, so the wheelbases are not the same.

There have been some interesting conversions done using the square-body Blazer chassis's and early cabs. If you do, you're going to have to shorten your bed to make it look "right". But, it's been done and may be a less of the two evils option.
