Ford 9" in 1965 Barracuda...an option?

I have 9” out a Lincoln Versailles. Fairly easy to install. I adapted e-brake cables and had a custom driveshaft built. 9” fords parts a lot cheaper and easier to find than 8.75. Due to the configuration of the ring and pinion you will need the proper gear oil from Currie.
Why Run Conventional Gear Oil?
My 71 came with a Versailles rear, it fit perfectly. I replaced it because of the brakes, the odd offset on the axle, and the rotation on the housing ends. I've still got it, buy the 4.11 center section, get all the other parts for free. But I'm not shipping it so it'll probably still be here when I die.
