dude any brand cap and rotor should work fine as long as its for the right motor. MSD cap and rotor should work just fine with crane ign. I have MSD 6AL, MSD blaster coil, MSD Cap and rotor, Ford distributor and everything works fine, I have also used ACCEL cap and rotor and Ford and it was fine too.
NO problems!!!
Stock distributor, MSD cap and rotor, MSD 6al, Crane Fireball ps91 coil.
Had an MSD distributor too but the module failed after 100 miles so I sent it back for a refund and put the stock one back in.
