Decoding/Numbers / BR Axle Code On A Z28
« on: January 04, 2007, 06:19:39 PM »
I have the protecto plate for my '69 Z28 but am puzzled about the "BR" axle code it shows. The axle code on the protecto plate is BR0218G and the car has an 02D production date on the trim tag. I was under the impression a "BU" code (3.73 axle ratio) was standard on a Z28. I have been able to contact the original owner of the car and she said the car was purchased new in 1969 from their local Chevy dealer but was not special ordered. What axle ratio is coded "BR" and why would one be installed on a non special ordered car? Thanks for your comments.
