    Recently Ground Up sent me their prototype for the 78-81 radiator core support for initial test fitting. I took a bunch of pictures and noted the differences and sent them to Paul but I also want to post it here for anyone who will be looking at this for a replacement in the future.

    First off, this part is excellently manufactured and nearly spot on in every way however there are a few differences that the 100% original purist restorer may not like but I'll cover those minor details.

    Additional parts used throughout the install for reference.
    Aftermarkter passenger wheel well
    Original driver wheel well
    aftermarket radiator support cover
    engineered cooling products radiator
    energy suspension solid 1" drop bushing set
    Fbody warehouse front end bolt kit
    original hood latch

    That being said on to the pics and the details.

    Now some side by side comparison

    On the 2 below pictures notice how the holes are punched out differently. The original is punched out at almost 90 degrees and the new one is punched out near 45 degrees

    The below two pics shows the differences in the nut sizes being used. The bead rolls look identical.

    Not a lot of difference here from what was already mentioned above about the holes.

    No more cheap repair for the mount location for the bushings.

    New passenger side wheel well fitment. Here the bolts where extremely tight fitting as if the two holes where spaced to closely together. This is an aftermarkter wheel well and could be the reason for this tight fitment because the drivers side is perfect with an original wheel well.

    Radiator mounts. Notice the radiator sits slightly outside of the mounting location. It was extremely tight on the original but on the aftermarket core support it just barely will not sit 100% correctly. The radiator is a engineered cooling products triple row.

    Passenger side wheel well fitment. Perfect no issues

    And here is the biggest install tip I can give someone. Remove your radiator completely and do not simply work around to avoid draining!!! You might just end up with a small hole in your radiator!

    Honestly I don't understand what makes reproduction parts so difficult to get right. Don't they have an original to compare to? Take measurements and make sure it meets spec? I can't believe the reproduction parts that not only have visual differences but don't fit either.

    I called Ground UP for info on when it would be ready for sale and a price, they did not know the answer to both. Wait and see.
