1970 Valiant Disc Brake Conversion

hi folks, am new to Mopar. All help really appreciated. bought 1 owner 70 valiant duster, slant 225 3 speed for hobby project with kid. anyone recommend a drop in front disc brake conversion kit, believe will need new master cyl and power booster (likely). is drum at all 4 corners. wheels are orig 175 x14. have looked at SSBC and Summit but unsure on best approach. thank you .

You need to make some decisions before we can answer your question. Do you want to stay with the tiny wheels? If so then your options are going to be limited for brakes. If you are willing to convert to big bolt pattern 15 inch wheels then you can put some real brakes on the car.
