tiny 140 mm clutch disc (stock A-series disc is 180 mm)

260Z input shaft (5-speed) is 1" x 24T
A-series is 13/16" x 24T or 18T
so the input shaft can be machined down to smaller diameter and then re-splined

Also to fit the 5-speed input shaft to the A-series crank, the pilot end of the shaft can be machined from 16 mm down to fit the A-series 12.2 mm spigot bush bore, not sure what the exact finished size of the shaft should be

"so the input shaft can be machined down to smaller diameter and then re-splined"
no need to respline the input shaft!
you just need a clutch plate with that spline
or get your chosen plate modded for one

Yes, I reckon when Simon modded this 71B gearbox to fit the A-series that he modded the shaft to take a stock 1200 clutch

I he just left the spline alone then a factory stock clutch would fit the A-flywheel (the HB210 clutch or L14 clutch) ... and then maybe he would have had less trouble finding a 5" clutch to fit
