Thought I would share how I fitted my 3 point harness to the beast.
It looks good and is also useable.
I bought this from fleabay for about £25
The SPARCO pads were a fiver from fleabay which look very good and are comfortable too.
It basically uses the same bolt fixings as the seat belt which remains for every day driving.
Here are the pics of the harness with the fixing points I used.
I will answer any questions that are posted here on this thread
PS....do the Carrelli's look good or what ?

Very Racey

Are they three-Point? I had them in "baby malc" 106 Rallye and I didn't feel safe with them for some reason I'd have four-point if I ever went for harnesses again. Carelli's do look
