SOLD! I have a couple NOS folding key blanks, the real deal. Great condition and ready to be cut to match your 02's key.
However, there is a "catch" - they're technically early 1600 blanks (1966-67). What's that mean? Well, the plastic bit is identical, but the metal portion is a few mm shorter than a 68-76 blank. Fortunately, there's a simple solution! I will also send you a 68-76 metal key blank that you (or a local locksmith) can trim to fit in the folding, plastic housing. I trimmed my 02's original key using a dremel and it works like a charm!
Price is $100 shipped for a NOS folding blank AND a regular blank to trim to fit.
Left is a 68-76 blank, right is a 66-67 blank. Note the slight difference in length.
