DUAL CALIPER MK1 celica supra QUESTIONS

[GreenLantern]

Does anyone make a dual caliper bracket for the mk1 celica rear end? Or AE for that matter? And would the AE and mk1 bracket be the same? Since I found the calipers and rotors are different size I'm assuming I may be able to use the AE bracket if I use two pairs of AE calipers and matching rotors/backing plates? If anyone can shed some light that would be great. Thanks
