Hi folks,

I have a very nice 3.36 positrac carrier from a 1958 Corvette that came out of my dad's 61 Corvette back in the 1990s when he swapped it out for a 4-series gear. It is in nice shape and always operated quietly in the car. He has owned the car since 1963 and I know it hasn't been beat on too hard under his ownership. Date code is December 1957 and the case is embossed with the tall 'P'. Axle code is too tough to read without stripping the paint. Any idea what it is worth?

Thanks!
