If you buy a corona front cut (TT144) then you will get everything. I think the corssmember would be a bit different, you could just cut and weld your one where needed. The same issues aply with this as will any conversion, and the engine does fit in that car (it was a factory thing). The rear brakes do not need changing. I would recomend you upgrade to vented front disks, off a RA65 celica or something similar.
