Brad, yes indeed all those 73 parts will in fact bolt on with no problems. However, as was mentioned if you plan to use the verticle flow rad you will need to make a set of offset adapter brackets to compensate for different mounting application. I can send you a picture of the brackets I made if you like. I dont know what it would look like if you used the early grill but that would be an option as well. The holes in the 73 front section are larger than required for your existing bumper brackets but that as well should pose no major problem.
