Ol RustyCranks 74 Dart

It drives really, REALLY well. The drums all around actually work very well. It has power steering that is operating great. Trans shifts well and pulls strong with firm shifts. Ive got a 66 Bronco that doesn't have a straight panel on it that's going to donate its 9in rear with 4.11 gears. Maybe I can sell the top and tub to recoup some cash. Ive looked up the measurements and I think the 9in is about 1 to 1.5in wider. But for now im gonna drive it with the /6 and enjoy it some before I pull the engine and trans and give back to the previous owner. After that look out springs, I think they need to move in a bit and then the heart transplant. Im wanting to drop in a 360 while Im waiting on the 340 build but im stuck between a 904 or 727 tranny. I know the 727 stronger but I think the cons outweigh the pros considering what else Ill have to change. Any thoughts on this would be appreciated.
