I apologise if this is wasting your time, TWR, but have you been searching using the correct spelling? I note that you've typed 'Couger' in your question, rather than 'Cougar'. Using the correct spelling brings up several possible items on eBay.
Hi Tamborine, the book I gather is very hard to come by, I have gone as far as EBay Germany as the car was part assembled there, there is a UK Spec also USA Spec, but grateful for your help, it's a pity that a few more never came up with your suggestion instead of ???? what can I say, only I am not in their league, & no, I am not a touchy person! the grammar may not be perfect, but we all have problems?? don't we. Again, thank you Tamborine.
