1966 Rear End Swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

about my old rear end?

i dont know, i havent given it much thought.

it has 3.73 gears (confirmed by counting ring and pinion teeth and dividing the # of ring teeth by the # of pinion teeth)--but i dont think it's posi.

I read on the Internet (yeah, i know...), that limited-slip gears ARE posi-trac gears.

i thought limited-slip only transferred torque/power to one rear wheel. whereas posi-trac transferred torque/power to both rear wheels.

now, i'm totally confused. =(

how do i go about confirming if a rear end is posi or not?
