I bought this rig to drive the snot out of until I can get the Buick built. It's got a 350 4 speed with the original 7.5 non-posi rear,I soon got tired of the mindless spinning and I installed a Powertrax to hook-up BOTH wheels. Being the hero I am it was straight to our local track,I eased out of the hole in time trials,spinning a little bit which was fine Then came first round of eliminations,I get excited,too much rpm,too much bite. It's fixed and going racing this weekend ou: The Buick is definitely going to need some Quality axles. :Smarty: TorqueRules
If that 7.5 rear breaks again, a '75-'76 Cosworth Vega rear will bolt right in-3.73 posi gears and heavier duty carrier!
