Thanks Andy. Pretty comprehensive article. Lots of good info all in one place. I plan on making the disc brake swap for my 74 Duster an up coming winter project. I really like the authors approach - using existing parts when possible. Even here in the Phoenix, Az area finding 70's and early 80's stuff in the local bone yards is becoming a challenge. Gotta start by doing some measuring on my existing 74 ( originally a /6 car - all drum brake ) Duster. Per all I have read, car should have the larger ball joints and spindle bearings as OEM. Looks like the spindles gotta go anyway. I have been through the entire brake system as it is and with the added weight of a small block motor up front, they aint too good. This car also came with NO sway bars, so I have installed addco bars front and rear. The added bars along with some offset upper control arm bushings ( to get the camber in spec ), the car handles great. Don't want to mess it up by changing the spindle ball joint dimensions. I will probably go with an adjustable proportioning valve, as this car also came with the small 7 1/4" rear axle - which will be another upgrade I will make after the brakes. Thanks again for the article. John
