Re: 3.73 posi setup

This may sound a bit foolish, but is this a stock rear end or are the Eaton unit and the 28 spline axles upgrades?

Re: 3.73 posi setup

Hello,

I have a 88 formula with a stock open 2.73 drum rear, this seems to be what I'm looking for, I'd like some pictures of it please.

Also, my offer is $500, only because it's drum brakes, and It's going to take me some time and money to convert it to disc, as I'm dropping in a 300hp+ vortech 350, I'll need the braking power in the rear.

Are the brake lines also on it?

Also, I'm in St. Louis, MO, roughly 4 hours or so from you, I'm very serious and would like to meet half way, as I can't drive 8 hours combined, it's impossible due to my work schedule.

Let me know,
Thanks.

Re: 3.73 posi setup

tswaim the eaton unit and the gears are the upgrades. all firebirds in 91 had 28 splined axles

mischief it has the brake lines on it. i did notice today that an axel seal is leaking on the left side. isnt too hard to do takes me bout an hour to do one and axles should have to come out to pull the backing plate off.
i can do 500 but if you want me to drive out there id kinda like an extra 50 bux for the time and gas.
theres a town called st francisville just south of the ia, mo border. that would work best for me. let me know what you wanna do

Re: 3.73 posi setup

FYI, unless the car is fully loaded, the rears don't do much stopping thanks to the proportioning valve.
