63-66 Grill hood bumper differences

[kizer]

Is there really any differences from 63-66 on the grill, hood and bumper.

I'm trying to find a few parts to improve and make my job a little easier. I've found a few parts that I might be able to wheel and deal with, but I'd hate to make the 60minute drive down to look at them and pick them up and find out they are not going to fit anyways.

I have a 1965 C10 and since these appear to be of the same C10 family I'm really interested.
