[SCG] 1964 Decklid update

Mon Oct 31 20:59:47 EST 2005

GM had an internal obligation that they also made to the dealer network
that they would keep certain parts (like sheet metal, emblems, etc.) as
active replacement parts for a minimum of 10-12 years after a model year
had ceased production, That also was a commitment they signed on to their
suppliers to keep tooling active until they gave notification to their
suppliers that the part was discontinued and an order was given to scrap
tooling on their authority.  I have that documented (I have seen documents
on this) as I worked for a company that supplied aluminum trim parts for
Corvair, Impala, Chevelle, etc, in the 1960's here in Wisconsin. Other
companies had similar commitments (i.e. Hudson, Nash, AMC, and Chrysler),
but Chrysler typically kept tooling longer than AMC or GM (up to 20 years
before giving scrap orders) but the minium for keeping parts active was
10-12 years for them also. Those timeframes are much shorter now and are
more based on rate of sale and resulting inventory rather than good will
commitments. By the way, that deck lid could be had at your local Chevy
dealer even back in the very early 1980's.

There are many examples I can cite just with Corvairs like this that would
add to questions of why, oh why, would they do that, but simple things the
add of the brake line/brake hose combo on the '69 model, specific to that
year while they were already ready for complete shutdown. They could have
easily used a 60-68 hose. There is no documented reason why that was
changed.

As much as those stamped areas were perforated, that can be the simple
change out of just not having that part of the die perforate in that area.
Additionally, when you add operations for perforating, it just adds to
cost. Yes, they all did some crazy things back then.

Even if that is all so, why, oh why would they make the change only 4-5
months before the entire deck lid was to be scrapped (replaced by LM
design)?!!!
