The shift issue was the round bushing in the shift tunnel, failed into pieces. New rebuild kit from our host and all is well.

The electrical issue is solved, but I really don't know what I did to fix it. Replaced flasher w a generic FLAPS unit that actually made the problem worse (fuse blew quicker) but after a bunch of messing around with grounds and tidying up some old wiring bodges, and putting he original flasher back in, suddenly all is well.
