Anyone using a truck radiator?

A radiator warehouse has a 3 core 22 inch for a 72 pick-up for only $15 more than the stock one for my Valiant. The only difference I can see is that it is an 18X22 instead of 17X22. Some quick measuring makes it look like it would be to tall but I was hoping someone else had good luck using one or will I be stuck buying one I can't use. It also says it will fit in a Cuda. Thanks.
