Hey hows it goin...

I've got a line on a "82+ camaro firebird posi" called the guy and he says its a 3.13, i'm guessing its really a 3.23, the only problem is its a disc rear and i need a drum rear for specific reasons. Can this disc to drum conversion be done ?? My guess is no since there is some machine work that has to be done to go drum to disc...

If not...anyone have a posi rear in a 3.23 or numerically lower (3.08.2.73) in the Calgary area ??
