I bought a front bumper for my 67 Firebird from Classic Industries. It was a made in China bumper that would not fit without using brute force to make it fit. I had to use force to get the twist out of the bumper so it would fit. My biggest error was doing this. I should have just shipped it back then and there. Instead I went onward and with force, made it fit. After it was all insttalled I cleaned off all the white chrome compound and discovered severe grind marks in the bumper. I could not accept this and prepared to send it back. I was told that since it was installed and had bolt marks on it, that it was not returnable. I complained (without sucess)that it was not usable anyway and no one would want this bumper in the condition that it was in.
So BEWARE. I got burned.
