I recently removed my 7.3 radiator core support from my 97 F350.
Removal isn't a hard job by itself. Unexpected discoveries along the way can become separate projects. For example, I removed battery supports and other internal components to recondition them while everything was wide open.
Key to your success will be to take pictures, before and after, of everything you touch.
Baggies and labels where you put nuts, bolts, clips or anything else your remove. One baggie per component, label the bag, store with the component.
Do not disturb the AC coil. Protect it on both sides and suspend its weight so you don't damage the lines. Don't damage or stress it while removing the core!!!
Choose an OEM replacement radiator core if you can. Take the time to clean it up, inspect for fatigue cracks, weld seams up tight, use flexible seam seal to stop water penetration between tack welded parts, prime with two part primer and two part paint. If you go aftermarket, my research found the LMC truck aftermarket support is not bad for the price. (See video link below and no they don't pay me). It is vital to check the height and width dimensions of the replacement core upon arrival. Be sure the fender / hood gap lines will align after reassembly. If the size doesn't match the OEM unit you removed, send it back.
My original core support is being reconditioned because in New England there is no such thing as a rust free core support. Cost to get an OEM replacement from the Southwest region was ridiculously expensive and then those I looked at needed refurbishing.
Good luck!
