I had them deleted on mine '72 when I ordered it and it wasn't suppose to have a vinyl top, but was ordered as a demo, heads were shaved to 11.75-1, build date was April of '71, got it in November of ,71. It had mostly '71 parts, whole driveline plus extras. Those sly dealerships hopping up their demo models was par for the Big 3. Columbiaparts.com has bumperettes I believe. I have a set of OEM '73 bumpers from a parts car. Brackets for bumpers on late '72 on, were longer and had another bolt in the frame and bracket, can use them for pre'72 by cutting off the second hole. Don't ever use a bumper jack as it will bend the bumpers.....always, any style.
