adding posi to non posi car
I want to add posi to a stock single leg 69 GTO 8.2 rear. I was planning to go the aftermarket Eaton route, as a fellow PY'er pointed me a great deal (thanks pont406!). But I thought, before I spend the money, is that the best way to go or is a factory 4 pinion a better choice? This is for what will be a primarily street driven car with 3.55s most likely (although I haven't ruled out using a set of 3.90s too at this point). The engine/trans will be a mild 428 (+/-400hp) with a T-400. My thoughts are that I don't want to worry about leaving pieces of it all over the inside of the housing if I indulge in some spirited driving...which was the result of my old 2 pinion one.
Input pros and cons is appreciated. Dave |

Dave,
Can't speak for the longevity of either unit but if you are planning on street driving and/or any highway runs I'd stick to the 3.55s. Your 428 has more than enough torque to get the car moving quickly. Joe

We've used several of the Eaton posi units in 450+hp cars without any failures. I would recommend it.

Thanks for the replies guys. As there's a factory unit on ebay now and I just wasn't sure if this was the best way to go...sounds like it probably is.
