My Dart has been suffering since I've been working on my D100. I got the truck out of my shop and started fixing stuff on the Dart. New power steering pump, fixed the nagging leak at the water pump, secured the exhaust pipes and a new thermostat (I've got heat now!). I also got the 8 3/4 in. It is an original out of a 68 GTS. Angle of pix makes it look narrow, but it is Abody. I noticed the letter A stamped in the case near the center. It has 2.94 open but better than the 71/4-2.76. Now it's back in my shop getting all new brake components. I couldn't get the pedal feel right. Turned drums, new shoes, wheel cylinders and master cylinder. I'll have it back together this week.
