Here's a weird idea, when doing 24v Cos conversions sometimes people put the rev counter from the 24v Granada in the Sierra clocks (some standard v6 Sierra rev counters work with the 24v some don't by all accounts)


So, why not try finding a 8v mk3 Granada clock set and fitting the rev counter in some Sierra clocks, can't remember what the 16v Scorpio rev counters look like but the late mk3 Granada's (late K- M reg) look just like the Wolf rev counter but without the wolf.


Might just sort you out?


When people do the 24v rev counter swap it isn't a direct fit but they do go in with a little fettling.


Unless the whole point is you're wanting to rev to 10k then I've just wasted my time
