Hi I was hoping to fit my fly screen on my indy but whats the height on the screen before you have to have wipers etc fitted I know I could leave it off till after the test. Thanks Steve

its quite complex, depending on the height and position of the seat, but the IVA manual** does have the detail.

be prepared to make some 4 inch high blocks, plus string, protractor, and a spirit level...
