Just curious...a 1967 chevelle should have the narrow housing.I think they switched to the wider one officialy in 68 but I have one that I know came factory in a 67 elcamino and it is the same width as the 68 and up rears... hat narrow one isn't too easy to find anymore...might be worth a little bit to a guy restoring an old chevelle. Shame to bust it.
