    Hard to determine from parts catalog; Are the 3 rear most undershields different from 2.7 to 5.2?

    First pic is of 2.7 bumper with extension brackets for under shield attachment.

    The next picture is of a 5.2 bumper which has holes to the left and right of the exhaust outlet that I assume to for undershields?

    Yes brackets attach on the 5.2 version as opposed to the fiberglassed in versions of the 2.7.

    Thats what I thought. Thanks. It does not look like these brackets have a dedicated part number.
    Can't find them in the parts manual. Are the brackets all the same? 6 brackets?

    Those are not the OEM brackets. I might know someone who has a new set @Illyria I believe has them brand new for the 5.2 bumper.

    Contact Ross at GTCP. I 3D printed mine only to find out later he's got some used available from breaker cars.
