Bumper change, 75 to pre 75 bumper Options

[Micky M.]

Hi there,
I'm in the progress of swapping my 75 rubber bumper to the pre 75 steel bumper version.
In order to do it right I need the diameter of the holes to be drilled for the pre 75 bumper mounts.
It would be extremely helpfull if somebody who owns a pre 75 car could give me the exact measurements of the location of the mounting holes.

Thanks a lot!

greetings from Germany....

I back dated my 75. I found the measurements in on the rear in the referenced thread to be close but just slightly off on my 75. I have a 73 as well to reference. I mounted the lower valance on the rear and set the taillight in place and then set the bumper where it needed to go.



I used someone else suggestion of short studs and a little dark grease on the dog bones to get the exact locations.
Below are the measurements I got when done. Over all process worked well.









On front holes are marked as indicated in referenced thread.

I ended up making a whole new front channel as I had some slight rust under the original.



I have changed to studs on my 73 and it makes installation a easy one person job.

Hope this helps.
