Help with rotor's and calipers

[MikeW eh! from Canada]

I have an R34 ER N/A Model  BKGAREAR34EDA-ECA-. I found this forum and was using the rotor and caliper guild. However nothing seems to fit here in Canada. I also wanted to go back to the front 4 and rear 2 pot caliper and found some. I removed the rear left seized one and replaced it with the 2 pot, the caliper fits perfect but is wayyy off from covering the full rotor surface. Any help, I would appreciate thanks again. I will attach photo's if requested.

You need to also get the appropriate rotors to suit the turbo model brake calipers.
