Looking for exhaust parts fpr my 64 Chevy Impala. Would like to find exhaust pipes #42123 and #42124. Also tailpipes #48072 and 48124. These pipes can have surface rust from storage, or maybe even be good solid used pipes, because they are going to be used on a daily driver (rain or shine). I know that I can buy them new, but I am thinking that somebody must have some kicking around in their shop. Thanks for looking.
