Need opinions from DIY mechanics

I'm putting a limited slip differential in my 66 GTO so I don't have the 1 tire BO anymore. Gears are 3.55 and I've found an Eaton Posi and a Richmond Powertrax No-slip posi that would fit. Both around the same price, Powertrax about $70 cheaper. Which one is better/easier to install?

what rear end? are you buying new posi's?

I have the original BOP 3.55 open rear end, so both will just be able to fit in with replacing the spiders or whatever. Just not sure if the Eaton is worth the extra money.

I have absolutely no fucking idea...I'd suggest bringing it to a mechanic, or maybe trying to get on Overhauled. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Get the Eaton, from what I have heard, it is a much more durable unit. I have one in my 79 transam on 3.08 gears for the past 3 years with zero issues.

Call your ISP.

The powertrax is a good unit but the locking mechanism is a little harsh, I don't know anything about the eaton.

The powertrax just slips in the stock carrier where the spider gears went, they are easy to install.
