The standard Golf & Passat rear disc is p/n 811 615 301, this is actually the same disc as fitted to the Golf 2 1050cc front wheels,
You can also fit the 239×12 mm front discs as fitted to the Golf 2 1300cc to 1800cc models (55 to 90 bhp) P/N 321 615 301 to the rear of your Syncro,
You will need to space the caliper carriers out from the swing arm (as the brake disc less offset) I find that the Golf 2 Diesel exhaust manifold washers are ideal for this P/N – N 900 955 01
As you state you obtained your rear axle set up from Canada I presume that its the Passat version?
Thats the one with the bolt in crossbar (that runs through the spare wheel well?) for hanging the center rear diff mounting?
if so this is not compatable with any Golf Syncro fuel tank, so most people then use a fuel cell.
