76 Dart Front Big Bolt Pattern Disc Brakes on my 66 Valiant??

Hey everyone, I know that the front brakes are interchangeable throughout the years but I'm wanting to know if the front discs from a 76 Dart will bolt into my 66 Valiant??
I went to the junk yard yesterday and they had just gotten a 76 4door Dart in that hadn't been touched yet. I scored on the brakes!! I removed the spindles, rotors, dust shields, caliper brackets and calipers. All in pretty good condition. Big bolt pattern stuff too!

Hoping they will fit my Valiant but unsure of what years fit what.

I'm going to clean them up and repaint everything, put new bearings and get new ball joints, and have the rotors cleaned up.

Any help would be greatly appreciated!!
