CCW is the code for the original ratio; 3.31 open in this case. 0918 is the build month and day, September 18. B indicates the Buffalo, N.Y. plant.
Probably the 87890 is really 67890 and there probably is a 12345 just around the tube from it. This is a foundry casting number and essentially has no meaning pertaining to year/gear/etc. 1A8 doesn't ring a bell either. There is a casting date code for the center section in one of the webs but it's in the format of letter, number, number such as C 5 0 meaning March 5, 1970 See http://www.chevellestuff.com/qd/generic_rear_axle_info.htm Dale McIntosh <http://www.chevellecd.com> ChevelleCD.com <http://www.chevellestuff.com> ChevelleStuff.com _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of richard sierra Sent: Friday, August 15, 2008 11:56 AM To: The Chevelle Mailing List Subject: [Chevelle-list] Identify Numbers Can anyone tell me what the following number mean??
