I bought My project car and was able to start it and find it has a spun bearing, so i called all of auto part stores napa, autozone, pep boys...you name it i called. All of them said they don't carry them. They also mentioned the manufactur date, which is may 1984. I looked on ebay and there is a machine shop on there that has them but does the date matter? the ones on their didn't say a specific manufacturing date to my knowledge and i wanna order the right ones. So can anyone help please?
