Will this work (tail light question)

I have a tail light that has the amber cracked and there is this place where I can buy a lens that is missing a corner piece. but I have a corner piece for it. Will I be able to have a good lens when all is said and done?

Corner pieces are interchangeable... or at least on post 91 models

Well i wish you reasured me yesterday. I would have felt better. But thats behind the point. I bought that lens for 21.00 and that includes shipping!! This will replace my kicked in lens.
