Surely a Taiwan plant would be willing to buy the tooling if Ford intends to recycle it for scrap, no?
You've got two impossibilities there...
First off, Ford doesn't sell tooling. In order to use Ford tooling, you have to be a Licensee, and Ford ships you the tooling on loan.. When you're done or if you lose or cancel your license, Ford tells you where to ship it next, or permits you to destroy it.
Second, you cannot import tooling into Taiwan. Period. Most countries are like that. Even the U.S. I believe. It helps to protect your domestic industries and existing toolings.
On a related subject, is the current crop of Taiwan Mustang stampings of similar quality to sheetmetal produced from the original stampings?
That's too broad/vague of a question to provide a good answer. All I can give you is a vague answer. The current "crop" is a myriad of hundreds and hundreds and hundreds of toolings/stampings/assemblies, some of it really really old, some of it middle-ages, and some of it brand-spanking new.. Some of it replaced older/poorer toolings, and some of it was new items that never existed on the market.
IN GENERAL, the new stuff is really nice! But the differences and/or comparisons to original Ford can only be discovered in the details. And in some cases, original tooling stuff had its own issues (there was a run of original tooling fenders that were assembled so poorly, that our Golden Legion fenders fit better... That went on for over a year).
But some of the older stuff is also nice..
And then a lot of the older stuff is not near as nice as NOS or Original Tool.
It's an enormous grab-bag. You cannot "generalize" with sheet metal as a category, it's pointless.
