I'm a bit confused by what you are trying to say here, but if you get stuck buying Whiteline gear, contact me direct by PM and I will sort it out by Australia Post mail from the east coast of this country.
The AE86 rear axle is something like 1410mm wide compared to a TA27 that is either 1280 or 1374mm wide, so you will, at a minimum, have to fit fender flares to the rear panels to cover your tyres.
