Disc Fitment help '73 Duster

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...

Thank you for any help.

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.
