Funny, with all the legendary folklore surrounding 64'-65' Factory experimental parts being expressed by the water cooler for years now, it has just dawned on me, I've never seen an actual Magnesium K-member in photo, authorized print, swaps meets or part of any personal collections.
What insights this is the recent Don Fezell's ultra rare collection up for grabs. If anyone would have had a Mag-K, it would have been this gentleman.

Even Big foot has more supposed sitings then this mythical Magnesium Ninja.

Contrary to all of this, I've heard from some Chrysler sources of special metal part stampings after midnight at the foundries.

Maybe self interest mojo? or hidden undocumented truth?
