A friend of mine was kind enough to make me a 26" radiator support. He is a half-pro, making the tooling for himself! I envy him because of his skills. I have not told him that though.
First he made one for himself. Once he had the tooling, it was an easy task to do yet another one. I might be able to persuade him to do one for you also but that will cost a couple of $$$.
Note that the car will not be 100% correct doing it this way. It will be good enough for me though. The washer bottle will cover most of seam anyway.
