i have a 65 fastback that is hobbling on a peg leg and i would like to give it a prosthetic for cheap. it has 2.80 gears. what can i do to get like a 3.73 ratio and posi? can i just switch the pumpkin? oh, it has a mild 289 that will be driven on weekends, car shows, cruises and such. if i only need the center section, does anyone have one for sale near ky? by the way, this site is awesome. so much useful information. i should have pics of the car soon. thanks.
