Thanks guys.....I've amended the sketch so the one above is the final cut.
I cut out the 4mm perspex today and this was the final result.

just a quick note...I had to use spacers between the perspex and the lower face of the tow eye. Since the tow eye is now upside down there is a groove at the rear of each leg of the tow eye that now needs filling or tightening the back two bolts will stress the perspex as there would be a void. I used 6mm plain nuts which fitted perfectly to fill the void as a spacer.
Had another run out (50 miles - mainly motorway) and the difference was well worth the couple of hours messing about. I'll keep an eye out for 'steering influence' from the perspex and if required will pepper-pot it with 6mm holes.
Costs:-
Superglue �1

Tools;-
Scissors
Stanley knife
6, 8, 20mm drill bits (I used the 20 for my brake lines)
Dremel with a cutting wheel for the perspex - makes a nice straight line.
