does anybody know what the wiper motor /wheel box tiger use? im thinking of fitting a full screen and the £135 or so that tiger want for one seems a bit extream! is it perpose made /adjusted by tiger or is it a production item i can pick up from a scrappy?

Dont know what Tiger use but on my last car I used a mini wiper motor and boxes. Easy to modify and fit. Also used cut down landrover blades.
I also used a Caterham heated windscreen from Red Line in Caterham. T'was very cheap and didnt require demisting vents.....Hang on...you've passed the SVA so what the hell, anything goes.

MG Midget setup is almost perfect. --- they turn up on ebay or from any of the MG breakers.
