Really Robin, how so? My research suggested that a Type-9 5th (0.82) wasn't quite as tall as a 25% OD. Was it something else he was suggesting? I agree with Clive about speaking to Mike Papworth before making a decision. Richard

Lawrence, if you want a lowwww-cost solution and you're willing to forgo the odometer/tripometer function (odometer - legal requirement??), you can make one with a voltage-sensing tacho. I did this on the Atlas with an ABS sensor on the output flange of the gearbox (sensing the 4 bolts). I was all prepared to calibrate the tacho (see Hugh Glossop's Courier article on 4- to 8-cylinder tacho conversion) but found that my 3.7 diff just happened to give bang-on callibration. Your type-9 will give X-many pulses per revolution and you can calculate the answer, or do it by trial and error. Richard

Here you go - Upgrading 1968~79 VW Type 2, front/rear wipers & washers, might give you some ideas. Richard

Saw an artical about doing this on a VW Type-2 Van and the author suggested using a pantograph wiper arm (from some sort of Vauxhall) so as to get good coverage with the offset (downwards) motor. Made me think of using a Stag wiper arm to keep it Triumph on the Atlas. Richard
