Can anyone identify what these front disc brakes are?

I feel kinda dumb asking as I SHOULD know; but I can’t recall honestly. 15 years ago I had a front disc conversion done to my ‘74 fj40. Original axle I’m pretty sure it was a mini truck swap out. I’m in need of new calipers rotors and pads and I just want to know what to order. I know it’s a bad pic and it’s dusty and crusty. Truck sat for a while.

solid rotor would be a mini truck,
vented rotor would be Landcruiser

can't tell from the pic

if mini truck solid rotor, the rotor and caliper can be changed out for Landcruiser

there may be some hole issues depending on what year hub and rotors you have, as the mounting of the rotor to the hub changed in 1981?? can't remember what year exactly
