Front bumper back dating, To cut or not to cut, that is the question? Options

[draganc]

Hi folks!

I hope everybody is doing well in these crazy times!

I have a’75 teener that I’m in the progress of bumper
back dating.

All of the thread that I read are pointing out that you
will have to trim/cut off the front “hook” lip that holds
the original bumper rubber in place.

Well, when I rest my aftermarket FG bumper on top
of the hook lip, it’s almost flush with the left and right
plane of the fender.

Which leads me to my question, do I really have to cut
off the hook lip from the body?

Do I have a “special” FG bumper (it’s black, new and
no visual markings - bought it from a Cali member but
forgot from whom).

Did anybody else had a close fit FG bumper? Did you
just trim the FG bumper instead of the actual front?

Thanks for sharing your experience and stay healthy!
