Windscreen wiper motor

[peterux]

I'm planning ahead and starting to scan eBay for some wiper bits.

I see Marlin fit a three wiper arms and blades system. And I've figured out the motor is a standard Lucas 14W two speed motor.
(SVC have a good article on their website.)

Does anyone know what drive gear should be fitted? (Apparantly they come in a range of 90 to 130 degrees) I'm guessing 90 or 95 degrees would be about right?
What angle drive gear comes in a standard mini motor?

I assume the wheel boxes are standard BL mini types?
What type of wheel boxes, 32 or 40 teeth?

What type/size of arms and blades are suitable?

Any info out there?

thanks

Peter
