Don't remember when I first heard the term "bird-bath" hood.
My first new vehicle was a '74 PW after I graduated HS in '73. I even considered drilling a couple of small holes in the hood to drain it but my Dad told me not to.
Really loved that truck even though it was a 318, 3 on-the-tree, PS, PB, sb and nothing else.
I've had other PWs through the years (new-'75, '78' '79 and a '74 and '79 I bought used) as well as an '82 and '85 PR but the '72-'80 body style is still my favorite. Keep hoping I'll run across a ClubCab sb PW at a decent price but around here they sell for almost B-J prices if they are in any kind of half-way decent shape.
