1970 Duster 318 with assorted parts, help

Where do I begin... I picked up a nice 70 Duster w/318 as a project car for my son and I.

Seemed like a great idea but driving it one day the brakes went out, to the floor nothing. I found that the front end came from another car, so I decided to pick up some disk brakes from a local auto dismantler who said the front end I got came from a 73/74 Duster and would just drop in.

After some weeks, lots of money at a mechanic the brakes were rebuilt and I went to assemble them. I have a shop manual and it appears that the lower ball joints are reversed, the brake calipers are on the front side of the car. the shop manual shows them on the rear. Is this possible, the mechaic says it will work don't worry, thats when I began to worry.

Does anyone have pictures of how it should look?

Also loooking for pictures to see how the Power steering pump mounts. I think I have the wrong style mount for this engine the water pump goes over the timing chain cover and there seems to be a bracket missing.

I would appreciate any help just trying to get this car back to stock instead of all the different types of parts it now has.

Thanks SM
