I think propshafts are the same PF and FL.
Boot was split on my PF, I discovered it when changing gearbox output flange seal in 2012. It looked like it's been split for a while and CV joint had been running dry and overheating and had burned on propshaft so it broke trying to get it off. It was made by GKN LOBRO, 100mm outer diameter, 32 mm wide and with 25 splines. They are used on several older cars mostly as inner driveshaft joints. GKN part number 21561 for CV joint, other cheap aftermarket versions are available, propshaft is rotating faster than driveshafts but lower angles so you need different boot that does not disintegrate at high speeds and high cetrifugal forces but fast boots are also available.
