70 charger drum to disc brake question

hi guys.. I am converting from drum to disc brakes.. do you guys think that the old spindles would work or do I need a kit that has the spindles? oh and what brand and where do you get it from and of course a good price..?? thanks

I have a couple kits that re-use your drum knuckles, and a few more that include new, disc knuckles.
