1970 Duster 318 with assorted parts, help

73+ disk brake spindles are symmetrical. If you install them on the wrong side, meaning that the calipers would end up in the front instead of the back, there is no harm but you may have some problems trying to get the stock sway bar back on(if equipped).

From www.moparts.com:

"geometry is fine, the knuckles are symmetrical. The problem is the brake hose. Some people have found solutions that work for them but it depends on which caliper you use.

If you don't rear-mount the calipers on a '67-'72 sway bar car, it will hit and take a way some steering range. Rear Mounting is easy...

If you are going to mount to the front, just use '76 Duster Calipers and Hoses, but for the rear, use the '80 volare stuff!"

I did this conversion on my 71 Demon. I used all 73 Dodge Dart parts. I mounted the calipers on the front and had no problem(i had no factory sway bar). They mention the hoses might be a problem but I had no difficulty installing mine. HOWEVER, in order to bleed the brakes, you will have to bleed them while they are NOT mounted to the spindle. When you put them on the front, the bleeder screw ends up towrds the bottom, making it impossible to get all the air out. It took me a while to figure that out. I had to hold the caliper in my hand with the bleeder screw up while my buddy pumped the brakes for me. After bleeding them, I installed them back on spindle. Worked like a charm.

I recently added an aftermarket sway bar from Firm Feel, Inc. (www.firmfeel.com) They make sway bar kits for cars that originally didn't come with sway bars. IT FIT GREAT and cleared the front mounted calipers.
