Got carried away!

[Lynn Eades]

At the rear, there are two similar boxed steel things. the mangled one with the stud is the same size as the good one, except the top is open. They hold the jack handle. A strap is fixed to the opposite side to the stud, and comes down onto the stud to hold the two extention halves and the handle in.
The fitting at the right locates the business end of the crank handle.
Bolted to the rear upper plate, above the jack handle is the big armoured battery box (two rows of 3/8 bolt holes) This has the POL box bolted to the back of it, which in turn has the number plate board (steel) This has the tail light mounted on it.
That number up the front, Can you post a picture of it?
