Howdy, im going to be replacing the outer side cowl panels on my 57 gmc and had a qestion. American classic parts show that there are two panels on each side, an inner and an outer, but then most of the other parts sites only have the outer. I have the top center cowl panel off so i can see down the sides and there doesnt seem to be an inner panel. So I guess my question is am I going to need both?

Has anybody replaced these before and can give some insight?
Thanks
