1973 Dart Swinger Drum to disc

Thank you all for the information on swapping to disc brakes.
I checked out the Dr Diff website and also CPP website. I don't know about Dr Diff but CPP has a complete B body kit including booster, MC and upper control arms that looks promising. I suspected the BC was different and prefer the LBC. I plan on upgrading the anemic 7.25 open diff with an 8.75 posi, if I can find a housing and will go with LBC axels. I already replaced the original 4 leaf rear springs with 6 leaf. Still debating on changing out the .82 torsion bars to .87 or larger. Definitely adding a sway bar and upgraded shocks.
I added pictures of the car after changing out the leaf springs and spending 6 hours buffing out the paint.
