Hi Julian
Not sure if they are worth having at all. The GTD used custom drive shafts made by Jack Knight Racing of Woking. These fitted onto drive shaft adapters with Granada CV joints on the gearbox and to the Granada CV joints at the wheel end. You know this bit but others might not! Therefore I would suspect that Renault items are of no use to you.
A number of us just had a number of shafts made and these came out at about £100 each plus VAT. However there was a min order quantity to get that price. A sole pair of shafts would cost a bit more but you can only ask. I would guess at £150 each. Club together and go for discount.
When we went to Quaife they seemed interested in making some and would be happy to try and beat JK prices. Both companies offered to make out of stronger materials if required. I don't think that would be necessary.
JK already has the pattern but Quaife would need one to start off from.
Hope this is of help
Malcolm
