I'm in the process of swapping my 12-bolt for a 9"... the center section is a stock 78 Ford truck 31-spline 3.50 posi. The housing and axles are Moser Engineering from "big gear head" Freddie Byars.
Also adding a Hellwig chassis-mounted adjustable rate rear sway-bar, and some adjustable rear Varishocks. This will add a lot more tuneability to my setup, which I desperately needed... was really band-aiding the balance with stiff springs that were under-dampened last year.
I didn't take a pic tonight, but I've got everything in now, just need to to tighten up the sway-bar, stick some springs in, and bleed the brakes. Also looks like I might need a new driveshaft...
