[Healeys] Overdrive works switch

[John Rowe]

The works cars had the overdrive switch on the firewall removed so you could 
just switch into overdrive when you liked.

If you just treat it like another gear and just touch the clutch when you 
change so it is not changing under full power it gives you a very quick 
change.

I use it all the time this way in Tarmac Rallying and it works a treat. It's 
especially good if you have Sebring style gear ratios where you have a close 
ratio box and the o/d is 5th gear.
