This is the ultimate rear end for any hot rod. A little costly but hey if you are building your dream it has to be there.

Would Recommend

Not your usual rear end.

If you don't want your usual 9 inch in your rod, this rear end is for you. Its expensive but when you want your rod built your way, it can sometimes cost more.

I talked to a fellow at Winters. He recommended the SR2550STB rear end. He also suggested the Willwood disc/ebrake kit. Do you have a part number and cost for this kit. Also do you have any suspension kits specific to the quick change and a 1940 Ford coupe. Thank you

Is it possible to adapt '39 Lincoln Style backing plates, and Buick Aluminum Brake Drums to this Differential? If so what is needed? I already have the Brake Drums and Backing Plates. This is going into a fenderless '27 T with Mild Flathead, and 5Speed.
