Unobtainium – What To Do? Where to Call?

As technology progresses, some things do get left behind. Trying to find parts for an older car might send you to the dealer, an aftermarket shop, the Internet, or that sad realization that not only is it no longer made, the manufacturer is out of business, and since no one can make money making and stocking the part, it may have moved to the category of “unobtainium.”

Still, with the worldwide access via the Internet, it is amazing how some things can be found – or a replacement for them fitted. This page hopes to not only help identify problem parts, but what options might be available. If you have information to add, please let us know!

There also is a new page of hard to find transmitter parts that might be of help to you.

And, then there is this:
