can someone tell me the differences in the 63 -64 years will they work on either car?

The difference is the trim on the front edge. The 63 has holes for the Plymouth letters and 64 has larger holes for the piece of trim across the front edge. They will fit either one.

Yup ^^^

thanks guys

Yep they are the same. My glass hood I bought from a friend and he had bought it for a 64. But as said the only difference is the 64 gets the mld that goes across the front of the whole hood. And the 63 just gets the Plymouth letters. Ron

There also is a very slight difference in the relief for hand to get to the hood release lever, but it not a difference that very many people would notice. The only reason I know is I have a 63 hood on one of my cars and a 64 on the other.

Yes, I had a 63 way back when, the hood got damaged and I replaced it with a 64 and this was the only difference I can recall.
