Title: 67 RS/SS BB rear axle ratio's?
Post by: erb2820 on March 18, 2009, 04:48:12 PM

I have a 67 RS/SS BB NOM and have a 12 bolt 3.55 posi gear ratio in the rear.  I have a 255 R70 15 inch wheel in the back and I want to replace this with either a 4.10 or 4.11 posi to get the punchy feel.  Did either gear ratio exist then, and any suggestions on brands, and what to look out for when having it done.  Thanks!!

The 4.10 : 1 axle ratio was available from the factory for the 1967 Camaro.
