Best to check.....have acquired a set of WR7DC single electrode (for lpg) but the forum recommended type is W7DC. What is the difference? I know some plugs require non-resistive ignition leads as the resistor is in the plug core but not sure what the 'R' represents in a Bosch.

Yes they are fine, the R stands for resistor, ideal for the electronic ignition systems on your engine.
