    They are GM NOS replacement hoods that have the holes for the air induction scoop. Born with 70 hoods did not have the holes. I have parted quite a few 70's and came across both style hoods...

    Chuck,
    I posted some photos of an original 70-73 R/S inner fender (GM # 3974542) as well as a NOS 337462 74-77 R/S inner fender on 04/02/2011. I can post the photos again or take some additional photos as I still have them.

    Dave, When I click/look at your IMGUR photos, I only see one pic of a fuel pump.
    What if anything am I doing wrong ????

    Dave, 1) Can you also document changes/differences in the core support where the
    front flange of the inner fender bolts to the core support. I'm writing about the
    step or uneven surface of the support and the offset of the inner fender.

    2) Can you also write about/ show the large opening core supports used on the Big Block,
    Z/28 & A/C cars. There is a large one inch (??) hole pierced in these supports where
    a ??? passes thru ????.

    Chuck,
    I have no idea why a fuel pump shows up when you click on my IMGUR photos.
    1. Attached is a photo of the front part of a NOS 337462 R/S 74-77 inner fender.
    The 2nd photo is the front part of a used original 1970 3974542 R/S inner fender (same as 71-73).
    They look the same.
    2. I have an original 1970 Z28/AC radiator core support in my garage attic. I don't think that I ever took photos of it but maybe I did. I'm not sure exactly what you want.

    Dave, I respectfully write the front flange/edge is Not The Same
    in your above two pics

    Your top picture shows how the inside (toward the engine) fastener
    location is Offset to The Rear
    whereas in the lower picture the front flange/edge appears relatively
    straight...........

    This right side is covered by the battery tray so impossible to see in
    a complete car.....

    All my loose core supports (from 70-73 Camaros [I think] ) have the uneven
    offset surface to accomodate the offset/stepped flange in upper picture.

    I will next bolt together my loose inner fenders and loose core supports
    and take/post new pics

    Chuck,
    OK, I now see in my photos that the NOS 73-77 inner fender is offset to the rear while the 70-73 inner fender is straight.
    I took a look at the lower R/S of my rusted original 70 Z28 radiator core support that is up in my garage attic. I'm still not sure what you want to know. Maybe your photos will help.

    Are you looking to sell any of the inner fenders?

    Dave, I'm quite sure I have correct 70-7?? R & L First design fender wells
    (at least 1 pr for my 70 R/S Z28).......but how exactly did the 74+ Core
    support change to match up with the offset/stepped front edge fenderwells.

    I have several core supports here...........and believe they are all 70-73 but
    wanted to learn the 74 change......

    Can you also write about/ show the large opening core supports used on the Big Block,
    Z/28 & A/C cars. There is a large one inch (??) hole pierced in these supports where
    a ??? passes thru ????.
