I don't know the year of them. Their is supposed to be a ID tag on them but they are long gone. Can anyone tell me what year they are? Here are some pics. Thanks, Todd Their are 2 different numbers that I found. 4525 is stamped right where the baseplate meets the intake 57 is stamped where the baseplate meets the carb body. Thanks again!! http://www.jalopyjournal.com/forum/attachment.php?attachmentid=972607&d=1273523626 http://www.jalopyjournal.com/forum/attachment.php?attachmentid=972608&d=1273523626 Last edited by TPost; 05/10/10 08:12 PM.
