With new paint, you will need at least 2 extra people which you thoroughly trust to keep the the rear of the fenders from gouging the cab and and hitting the running board brackets.
Personally I do not see how the entire front clip can be pre-assembled off of the truck any easier than assembling the pieces individually on the truck.
I thoroughly understand how it makes sense to remove an existing front clip from a truck, then putting it back on the truck as one piece, but that is an entirely different scenario.
My 15 cents (adjusted for inflation).
