Has anyone on the 72-79 forum has done this swap already

 

None that I recall. There are a couple of guys in the Bumpside forum who have completed it (elgemcdlf, carcrafter22) and a couple of others who are in the process.

And this is the 73-79 forum. Dats okay, I fat-finger the keyboard all the time!!

 

I am in the process of doing it now to my 74 swb. The rear has been flipped with an Explorer rear and now measuring before cutting out the front. Been kinda time consuming since redoing the box, swapping cab/front clip from a 78 and ditching the 300/c6 for the 400 from the 78 but the stock front is coming out this week.

Are/have you started the CV swap?
