Injection moulding or wheel arch moulds GTS arhces

[GTSPhil]

Hi Guys

So to make a very long story short.

I have been after someone that has or can get or can have a set of moulds made for the Original GTS wheel arches for preferably Injection moulding them back to original spec. 
Next option does anyone know which company used to supply these wheel arches to Leyland back in the day?

I have been listening to the same stories from the same people for quite some time about having moulds made.

I know of the arches that is available sometimes in fiberglass, not specifically what I am after if I have a choice.

I have been told by numerous people that the correct way to make a mould is with the arches still on the car,  if need be I am willing to go down this route, now comes the question of money into play.  If needed I am willing to pay to have the moulds made and to provide the car with the arches in reasonable condition, but within reason on the financial front.

I do fully understand that the demand for such arches is very low, so that begs the next question just how many arches will be sold if correct nice moulds are available to supply said arches?

If possible can I be referred to a injection moulding company or specialist in the gauteng (PTA or JHB area) please.

Thanks
