I have a 73 G/A front bumper with the rub strip that has come apart from the metal backing that bolts to the bumper, & I'm wondering how to or what I need to glue or fasten the new metal strip with the small bolts in it bact to the rub strip. The rub strip is made of a heavy rubber similar to a 69 front bumper , (I think) & there was a metal strip behinde it with small 5/16 bolts in the strip & it WAS fastened to the rub strip. I made a new metal piece with the bolts but need to know what to use so it will stay glued to the rub strip. The back of the rub strip has indents were it sits in/on the rub strip for alignemnet. Any help will be appericated/
