Its a stock 318 challenger -
I don't believe the k-frame needs to change?
I know for sure need to change the auto transmission to 727,
drive shaft, rear end axle and differential.
ADD sway bars front and rear, HD brakes and
HD torsion bars.
I think you need to find out what you have before you start ordering parts.
My 73 Challenger had a 318 and came with an 8 3/4 rear axle. No need to change that out. If you currently have a 727 you can keep the driveshaft.
Sway bars aren't required, per se but you may already have a front one.
What brakes do you currently have?
