Wheel/Control Arm Clearance Question

[Jdm63]

Are there any known clearance issues using:
cpp 2" drop spindles
stock control arms
Disc brake conversion
with 15" wheels
1.5" or 2" drop coil springs

Wanting to use stock steel wheels if possible, knowing I may have to change to the later 5 lug wheel for brake clearance. Especially want to rule out any clearance problems with this set-up before proceeding with stock control arm paint and rebuild.
