I don't have any firsthand knowledge on these but have some experience on the 67-72 style which may or may not directly translate to the 73+ body styles.

The short answer is yes they can fit and should bolt in no problem at least cowl to fender-wise just fine.

The big issue you are going to run into is with grafting the medium duty front end to the light duty body (assuming you are using the light duty chassis) is that the medium duty fenders and hood are significantly shorter than the light duty parts. There would be a need for significant fabricating to make it fit/let alone lining up the wheel in the wheel well.

A smaller issue, but an issue nonetheless, is that the fenders and fender extensions cut into the lower corner of the door. This is in part to make way for the larger wheel/tires but also the inner fenders connect underneath the kick panels and actually cut into the firewall some for clearance. Now with those pics you posted, they don't look to be AS bad as the 67-72 but still something you should think about when going in.

Are you running the C30 frame and wanting to just install the C70 nose? Or are you swapping the C30 crew cab body onto the C70 frame?
