ford 9 inch 31 spline 3.50 trac lok differential

I got a ford 9 inch center section that i bought not to long ago for 500.00.I had my mechanic tell me this setup is for drag racing and not for street use.Not realizing thatthe trac lok was FULL TIME and i realized i cannot use it.I am going back to my limited slip and having a 3.50 gear put in it so the trac lok is up for sale.There isnt even 1 mile put on this thing it was tested up and down the road and that was it.It is just the center only and is NOT a N case as well.Its a brand new REBUILT setup i`m willing to let go for 350.00 FIRM!!!! I will post pics as soon as it comes home, its in a shiny black but also there is no bracket for the rubber snubber so if you got 1 you can use it on this or just use a drag loop.I`m located in hastings florida and i`m willing to ship this anywhere.

thanks
