How easy is this frame horn to repair?

[BB72CHEVKT]

I am buying a guys collection and this was one of his shotbeds. One of the other shortbed frames has had the frame horns are cut off. These are my two concerns about my the whole deal. There are two 69 SWB trucks one converted to 5 lug and one is a fleetside and one a stepside. There is also a seperate stepside bed. I will also be purchasing 5+doors, fenders cowls, a couple of hoods and 72 a/c cab, 90's bench all kinds of odds and ends, pullies, ram horns etc. One of the cabs may be too far gone. I forgot to get pics of the frame that was cut. Here are some pics.
