If earlier '82-84 CGT - need to swap front in too as earlier CGT is 4X100 vs. later 4x108 hubs.  Also front brakes are likely beefier, unless recipient is a later model.

Some other minor changes may be needed, but it is a relatively straightforward swap - providing you take everything off the 80/90 and don't try to mismatch calipers/carriers, disks,etc.  Otherwise, you may get into trouble.

Basically the swap should entail - entire trailing arm assembly incl. rear disks and brakes.  Should be around 6 bolts and two brake lines for the rear and the whole thing bolts right up.

Then you need the front strut assemblies with brakes, disks, etc. - press in new bearings recommended if unsure of mileage and condition. 

The parts to NOT USE unless you want a height increase is the springs which is appropriate for the installation of new/upgraded struts - just swap in the ones from the existing setup, but mostly use everything else off the M80/90.

Still working on '83 CGT turbo conversion which is using M80 rear axle, disks, brakes, etc.
