68-69 510 Rear Bumper Reproduction

[Dave Patten]

I need some help to reproduce the 68-69 510 Rear bumper.

I need the dimensions of the plate light hole in the US rear bumper, both size and location. I have the JDM/AU plate light configuration, but need to verify the US dimensions to compare any differences.

The dimensions needed are:

Length of hole (side to side on car)
Width of the hole (front to rear)
Distance from the hole to the forward edge of the bumper
Diameter of mounting screw holes
Center to center distance of the screw holes
And any other dimensions to the screw holes if not symmetrical to the main hole.

Any help that can be provided will be greatly appreciated.

Joel,
Thank you.

Turns out the pattern/dimensions are exact what is used for the JDM/AU bumpers.

So, when rear bumpers arrive FutoFab will also have 68-69 reproduction rears with the opening already in them.
