Concerning my 74 Camaro, pretty sure , my seat belt system is original to car , the interlock system even works . I fastened my belt into the receiver beside the driver seat today, and the receiver parts landed in my lap . It is a mostly plastic afair , the top of the buckle all ( plastic ) broke up and the rest flew out . Investigating ... I saw none on ebay that looked like mine , all on there was for 75-81 . Not even a used broken one ! I searched 70-73 receivers and there was none either . So , Im presuming mine is like those too ? Wondered what can be done short of putting a wrong latter year reciever in. Are there any repro parts to put the buckle snap assembly back to together ? ,That flat top plastic square piece that hold all the guts inside the reciever if its available as a repair item....might be all i really need ? Or is this something that dies and there is no fix ? Anybody got a used one for sale ?
