Dear Mr Erland My husbands grand fathers name was Oscar Kloster. he owned and ran a auto shop in east L.A in the 1950s but he was married to a grace kloster. these kloster came from Olso Norway. I don't think there the same ones your looking for. I don't think this is who your looking for But I thought I would let you know that a Kloster did have a auto shop in L.A.
