Any progress to report, Daniel?
Hi Roger and all,
Yes mate happy to report that I have purchased one from auto collectors supplies, just waiting for it to arrive. Thanks for your help and support with this.
Sorry I haven’t got back to you earlier, I have been travelling with work and couldn’t post replys for some reason? Let me say though,it was not what I would call a cheap exercise getting this part but I guess had I not pulled the box down in the first place and discovered the problem it may well have cost a lot more someday if she had run off the road! Interesting to note that on the auto collectors website when they show a listing of parts with a qty of 22, it actually means that they dont have any stock 
maybe its just to trick us all into thinking that the parts for our cars are readily available 
I will let you know when it arrives and how it all works out…Cheers
Dan,
That’s good news and bad news- did Collectors Choice give a reason why they say they have stock on hand when in fact they don’t? Where did you finally find the part? What did it cost?
I feel badly for leading you to this company; I will hesitate to recommend them again. 
Roger, don’t feel bad, I actually got the part through Collectors auto supply they were good to deal with! they have a couple of warehouses so it takes them a little time to get back to you from enquiry…not sure how there parts qty works but it does seem a bit confusing? The new worm gear and shaft ended up costing me $350 Ouch!! but as you can see from my earlier photo I needed to do something and in the end I was just happy to be able to get a brand new one. Thanks again for your help in tracking them down and the phone calls!!
Yes, that was the price they listed. I am happy they produced teh part w/o problems. I can overlook the "in stock " tally, as long as they deliver promptly.
I looked into the other source mentioned on this thread…they had power steering parts listed, but no manual steering parts, so it seems you were fortunate to get your (pricey)part in NEW condtion. I bet John Fowlie had a good used one for you, but now you are set.
