I looked at it a little today. Looks like you only cut the rear fenders? Can a 78/79 clear 37s with only 4"? I bet it could up front with minimal trimming, and it would fill out the rear fenderwell better.

You can do wontons, just more $$.

I thought the prerunner thing was just a bar. It is less gay then I thought but there is really nothing prerunner about a 79 Ford. I would just use that base you have and mount a winch on it, maybe run some tube out to the side to protect the grill.
