Anyone been able to get Slotted and drilled front rotors for a 79 F-250 with dual piston calipers.

I am going to install a rear disc conversion on my 79 F-250 2x4 Supercab shortbed. the kit comes with drilled and slotted rotors. I figure I would get the same for the front of the vehicle. Anyone have a part # and brand. I was able to find some for the 80-85 F250, any experts know if they will fit as well?
Thanks...Mo
