Hello Lessur,

ther should not be a problem with what you outline, and is how the MK1 overdrive worked with a column switch.

I've always disliked that arrangement. The switch gets in the way of turning on the wipers, and with no intermittant option you need to flick the wipers on and off a lot.
My modification has always been to use an overdrive gearstick with knob, and rewire the redundant O/D column lever to operate the wipers. Then you can easily give single flicks to the wipers, and you can use the overdrive one-handed in conjunction with the gear-lever.

Lovely stuff - just wanted to make sure that the lever will fit and work in the short term (I'm hoping to attend a classic car run in April so might not have sourced the OD stick by then). Long term plan will be to use the proper OD stick with the switch on the knob.

Both non o/drive and o/drive gear levers will fit. The 'ball' that fits in the selector slot is the same on all manual models.
When sourcing your overdrive gear lever, don't forget that facelift Mk2 models had a longer lever than earlier models. This was introduced to try and overcome gear change issues / baulking, with the somewhat blinkered logic that more leverage would cure the issue.
Also don't forget to get the anti rattle pin / plunger and spring at the bottom of the lever - they are commonly lost when the lever is removed.

Cheers Johnny, so in your opinion is the longer or shorter lever a better bet?

Being a bit of a stickler for originality, I would fit the longer lever to your car as that is what it should have. Even if you could only source the shorter lever, you shouldn't experience any problems as long as all the mechanicals were spot on. The longer lever was only to try and overcome issues that shouldn't really have been there in the first place if the clutch operation and hydraulics were functioning correctly.
A bit like fitting an adjustable push rod to the clutch slave cylinder, or welding a piece in to get more throw on the clutch. Just masking other issues in my opinion.
