Some newbie questions about bags and brakes
 

Hello,
I have a 70' Sb 2wd I want to do disc brakes in the front but do not know what year trucks or shops to get these from. Also I want to bag it I am not looking to drag but just get it down there I have JDM 3" drop control arms but do not know if I can use them with bags but input on kits, or where to get them would be great. ;)
