For now tho, here is the photo of stuart woods car with the strap installed
Stu has the rear screw and washer lifted up from the post slightly by one small washer. The clip end of the strap is made thicker slightly with a peice of chassis protection sheet which takes up any slack and makes the clip a secure fit.
And here is STU WOOD !!!!!!! I wanted to add an interview with stu but ran out of time really. Sorry Stu! thanks for all your help mate.
