This is the first time I've read this thread....... plastics such as the rain tray are done by injection molding. The plastic is heated and forced into a mold under preassure. Water then runs thru the mold and cools the plastic and the two parts of the mold come apart leaving you with the finished product.
To develop a mold to make new ones would cost about $20K (I had a buddy that worked at a local injection molding place)....that is if you were going to make them in any volume....such as producing 100,000 or so for a producton run of cars (why Porsche changed them after one or two years worth of production run I don't know). That would make the mold development per piece about $5 per. Pretty cheap in the cost of a $4,000 car.
I could make them, but the mold development cost would be around $3000 (that's estimated...might be higher) and if I had a perfect one to use as a pattern. What the final cost per piece would be depends on how much of a demand there is for them.
It's always the first one that costs the most.
Thats my point. If every 914, thru sometime late on '72 (I think that's when they changed) wanted one, it would be OK - that's about 40K 914's. Assuming the tray was made properly (& that a donor was available), the cost would be moderate. But, since there are probably less than 5K of these cars left in usable condition (excluding sixes, which didn't have it), the cost would be prohibitative.
What would I pay for one? Probably about $300. But that's me. I doubt that anyone else would have the slightest interest. I'm a little anal about this part - most are not.
What bothers me is that I know of two out there that are right. And I can't get my hands on either.
