Newly rebuilt, narrowed posi disc brake Ford 9" rearend ready for your Impala or many other cars! Came from a '77 Lincoln big body car so it had to be narrowed. It was narrowed by Dutchman Motorsports in Portland, they also made the brand new axles for it. It has a brand new Detroit Locker unit matched with new 4:11 gears, and new rotors and loaded calipers. The rearend measures 59" without the rotors, a stock Impala rearend is 61 1/2", so being shorter it's perfect, and a added plus for skirt riders! Also have from Empire Customs the lower trailing arm mounts and a wishbone mount for Impala. I have $2500 invested will let go for $2000 obo. Or I can make you a great deal including this rearend with the frame I'm trying to sell!
