Front Clip Swap?

[nico]

I am the proud owner of an 84 SWB Silverado that is in fairly good shape, but will be needing paint very soon. The previous owner buffed through the paint in several spots (body lines).

I am also a huge fan of the 73-80 front ends and have heard of people swapping parts to update the look of an early model, but never back-dating to the earlier look.

What all must be changed to accomplish the conversion? Core support, feders, hood, cowl, grill, lights, etc.? Is it a feasable swap?

I admit I will probably never do it, but have never seen it discussed before either...
