Joe, 1970 BB Nova does not use the metal T-clips...the 70 cars used a small plastic "button"....I know you can get these from National Nostalgic Nova. Not sure if they are sold separate or as part of a kit with the flap and bracket...I have got them from Wayne before..give them a call 717-252-4192 or 717-252-2383....tom
ps; you are a member of NNN, right..???
