£250 for a pair of early bay drum spindles to take 85.5 944 front brakes, 2 good used calipers, discs and a pair of 85.5 blasted and primed 944 hubs/studs/caps. Collect Leatherhead / VOWO show or post at your cost.
You will also need an adaptor kit at around £150 (some are less, some more) and as you need to remove the bearings to fit the spacers I'd suggest you change those for new while your at it.
