The word assurance, as it relates here, means you are assured of success in one method and not in another. It does not mean you will not have success. I hope he does not "try" the fab method, that way he won't hit the %0 number and waste a lot of time and money. Practice on the thing after you remove it if you want. If you get it right, sell it and maybe get some money back. Also, one can not assume there is a proficient metal shaper near without assuming there is a donor cab near. If the poster does not wish to do the work, a fabricator should have an easier time splicing than fabing.
