Removing a Monte Carlo bar is going to leave some extra holes that your going to get dinged for
Also not too easy to take out and replace some of those export braces since they fit real tightly
If you install a Monte Carlo Bar without drilling the extra hole on each side you don't have the extra hole on each side problem. I put a modified T nut and a very, very short bolt in the unused holes in the bar to simulate the full four mounting bolts per side installed. Then stuck a sheet of Teflon between the end brackets and the car body to reduce scratches. Ding went away. A hint, do not use a washer under the top bolts, they may scratch the under side of the hood's frame.
And a tight fitting Export brace is a symptom of why you need an export brace. Your front frame and front end sheet metal have succumbed to old age. All three of my Mustangs have the Ford made (sold by many Ford dealers before former Ford president, Jack Nasser stopped selling old and NOS parts) brace, C5ZZ-16A052-E, with the offset holes installed. The original pairs are on the shelf, cleaned, painted and wrapped, ready for use.
