Goal: I want to install a front disc kit.

Just picked this car up and I know very little-- Getting a little confused on measurement differences between 73' Dusters with discs and drum.

Originally a 1973 Duster w/ 225 and drum brakes
Currently has a 360 and I'm going to give it a bit more power -- street build.

It has has American Racing wheels - AR172 Baja
Which I believe are size: 15x? (7,8 or 10) pattern: 5x114.30
I dont know the offset or backspace because I cant measure the width of the rim.

I read that this kit is good, but will it fit? What other measurements factor in here...

From what I read on the link it should fit with little to no problem, can't speak from experience as I have not used one before, but the description indicates as long as you have 10 inch drums currently and a 15" rim with a center hole of at least 3.05" you should have no trouble, will be a solid upgrade to the car too. It will increase the front track width slightly, about .4 to .5 inch total.

If you have a 5 on 4.5" bolt pattern its not original to a 4 wheel drum 73.
Check for wheel adapters, or you may already have discs.
Either way you have to know what you have before you order parts for it.
Different spindles, different kits.
For your use factory parts are a good option imo.

update: looks like i was getting my measurements from the wrong wheel online. thank you -- saved me
 
So I have a 73 Duster with front drums and 14" wheels with a 5x4" bolt pattern.
Summit and Wildwood recommend different kits on their website... Very torn here
 
Dont forget the factory disc brakes as an option.
I'm running them and they work excellent.
