I care too! Also bit the bullet and spent $700 for a spare SKREEM to ensure my Crossfire's extended life.
Also noted that responders are geezers, like me, and are most likely retired with limited living contacts in business and/or government.
There is a strong need for the current unretired membership to run with the ball and seek a solution for long-term parts support.
Otherwise, the assured non-availability of replacement parts, such as SKREEMs and transponder chips will result in relegating our Crossfires to the scrap heap.
(BTW: I was able to still buy all of my '53 Packard's parts for restoration (288 CI Straight 8 engine with Ultramatic transmission) in the late '70s, 20 years after Packard faded into history.)
Cheers,

PS: In a bit of a funk after my Alma Mater lost to Army yesterday for the third year in a row...
Maybe next year Bill the Goat will give 'em the horn!
