Identify Disc Brakes on Dart?

Thanks for the responses guys!

Is the "track width" different from front to rear only on A-Bodies?

I owned a 71 Challenger for over 12 years, and never noticed a difference in width from front to rear.. This Dart, I could tell when I first laid eyes on it..

After reading all the replies, it seems like I should have had some issues with wheels on my Challenger that I didn't have..

The Challenger had its factory manual drum brakes front and rear. It came from the factory with 14 x 5 steel wheels, with dog dish caps and trim rings. I had 225/70/14 tires mounted on them.

Back in 1992, I wanted to replace those wheels with 15 x 7 steel wheels. I knew absolutely nothing about small bolt pattern / large bolt pattern, or that there even was such a thing or a difference. I went to two junk yards in Southern California, where I was living at the time. The first yard had a pair of 15 x 7 wheels marked as coming off a "73 Dodge Van". The second pair of 15 x 7, that I found, at another yard, were marked "77 Chrysler Cordoba".

The 73 Dodge Van wheels would mount on my Challenger's drums both front and rear without issue. The 77 Cordoba rims would only mount on the front drums, they would not mount on the rear drums. So the Van rims were on the rear, and the Cordoba rims on the front, for the last 6 years I owned the car, with my factory dog dish caps mounted on them, sans trim rings. All I needed to do to the rims, was have them sandblasted, then I painted them the body color GB5 Bright Blue Metallic. I mounted 245/60/15 Goodyear Eagle ST tires on them and the car looked pretty cool after that. Only issue was my turning radius was reduced somewhat with the wider rims / tires on the front.

From what I read, it sounds like my 73 and 77 rims should have been large bolt pattern, and my car's drums and original wheels should have been small bolt pattern..

And I just don't recall ever noticing any difference in track width from front to rear.. And I looked at the car a lot! I never tired of looking at it lol.
