OK I'm after some advice here, I'm an engine man, not a wiper one...
Barney the pretend S is a ~66 Deluxe shell, with RH park wipers- the PO managed to fit a Clubby 2 speed motor to the wiper rack somehow.
He had LH park arms but I've now fitted original RH ones for originality looks.
The switch is a headlamp one, I get the 2 speeds but have no Park function- but it would park wrong side anyway with Clubby motor, so I just park them 850 style.
So far, so good. But...
Problem:
The late rack obviously has more stroke than the early one- the wipers do 180* on the screen instead of 130* or whatever.
So, how do I fix this? will the later Oz rack boxes fit in the early scuttle, or do I destroke the crank on the motor somehow?
I would like to keep the 2 speed motor.
I'm open to suggestions.....

Thinking about solutions I'll possibly just fit a standard early (square) motor.
Can get 2 speeds with one electronically, like I did in 1967. It will RH park then, too.

Kev what if you replace the later 110* (?) wheel with an earlier 105* (?) wheel? You'll have to replace just the metal part with the centre spindle and not the plastic tooth gear because the triple rails on the back of the plastic gear are needed for the 2 speed operation (the single speed wipers only have a single rail). Am I making any sense at all?

The metal part is just a press fit inside the plastic tooth gear.



(though the photo above is the UK version with the different parking mechanism)

Hmmm... maybe, but I've got a spare Clubby motor same as what's in it, I'll have a look first how the crank attaches...
