My 29 Chevy 4 dr. sedan ate its tranny the other day. Am trying to locate a replacement. Mine is stamped #590391, below it is a Bowtie 12, and below that upside-down is B99,indicating the date of MFG. Anyone with a tranny for a 29 for sale,please reply to this--and I will E-Mail you for more info. Thanks, Pitman
