if you disconnect the handbrake cables, you can knock the handbrake rachet & spring out about 1/2 inch, give the rachet a good rub with wet & dry to remove all traces of rust, then drown it in wd-40, let it seep in, then plaster it in grease and knock the rachet back in
you can also use ford granada return springs which are stronger than the VAG items
this is the ford part nums for them
6 141 147 and 6 141 148
if your car has the later spec mk2 calipers with the handbrake cable on the rear of the caliper then yes they are a straight swap with the mk3 calipers
but if they are the earlier calipers then you need to reroute the handbrake cables
