Hello,

Just picked up my 1969 rear suspension pieces from Bair's Corvettes in Meadville, PA.

Very happy with the final parts and the staff at their shop.  I highly recommend them. Smiley

Ah... that really looks good! Smiley
I remember when I did my suspension a few years ago and yellowjacket was featured in VBP catalog.

Stamped code on bottom of differential cover.

Late production Heavy Duty 3:55 ratio September 2nd 1969 assembly build.

If I am correct in my assumptions then the casting number and stamped numbers further confirm the numbers matching aspect of the differential to the rest of the build dates of the car! Cheesy
