Can anyone tell me if you can use the rotors and calipers from the front of an 86 gl wagon ea82 for a rear disk brake conversion for my 84 4wd hatch ea81 in theory all I would need is a backing plate from a turbo wagon or am I way off do you think this is possible pm me with details

You cant use the front rotors and Caliper on the rear unless you fabricate a new bracket for the calipers. The rotor is larger in the rear, and the calipers are alot different.

In order to convert your hatch, you'll need the rear rotor, caliper & Backing plate from any 4WD Turbo EA82.

Has to be 4WD turbo to fit on EA81? I thought it was any 4WD with rear discs.

the rear discs were an option if they didn't come on a turbo car. You can use the discs from a 2wd EA82 BUT you'll need the 4wd hubs to make it work.

Check our Repair Manual. There's an extensive how-to written by me. The swap is very basic and about as bolt-on as you can get.

Rear disc's came on a bunch of different EA82 models. Like N/A GL10's, XTs and was an option for any EA82 if requested. Its just that ALL turbo EA82's will have disc brakes. The reason I tell people to look for turbo EA82's cause 100% of them will have rear disc's. If your car is 4WD, you will need 4WD rear disc's. If your car is 2WD, you'll have to get disc's from a FWD only EA82.
