Trying to Identify My Brake setup

[THE_OWL]

Happy New Years to Everyone.
I have a 78 or so F-150 front axle. It has been shortened to EB size.
The previous owner set it up with what he called Chevy Brakes.
From what I can tell, it is a chevy spindle and caliper, with a Ford rotor(5.5")
The rotor diameter is 11.9" and the thickness is 1.25".
I just picked up a set of really nice Wilwood calipers. but they are made for a .81" thickness rotor.
I really want to use these calipers, so Im hoping someone could help me identify my brake setup, tell me what rotors I have, and what rotors I can get to work with the calipers.
thanks in advance.

Well the backing plates are 10 bolt I think, but the rotors may be CJ 30 or Wagoneer.

Uh, I must've had one too many last night. CJ rotors are bolt on lockouts and Wagoneer are 6 lug! Sheesh what a 'tard.

They're definitely Ferd, maybe late TTB Bronco/F150?

Do you know of any rotors that will fit this in a .81" thickness ?
I cant seem to find detailed info on the net about rotor thickness.
