New-ish to these trucks, but I want to lower the rear end ratio on my '66. Not sure yet what ratio it is(4.10?orig. 6 cyl/3 spd.) but I'm taching almost 3,000 at 60 mph. With the current 350/4spd/245 tire combo I'm looking to bring it down to the 3.0-3.23 range. I'd like to retain the 6 bolt wheels for now so I'm curious what drum to drum rears interchange with the '66 trailing arm setup. I know I can get another R&P just looking for alternatives.

Any help or hints appreciated,
thanks,
Dave
