One option for Australian listers (sorry Larry), is to fit a modified Bosch
distributor from a GM Holden V8. Rangie Spares in Melbourne tel (03)
9464-4094 sell them. While we are talking replacement parts, the viscous
fan coupling from a late model Ford Falcon (late '80s) will fit the '86
Range Rover motor. Mine has the coupling and a cut-down Ford steel fan. I
think the later Falcons (1990 EA onward) use plastic fans but I'm not sure
