I hate how some dealer parts are obsolete after 10 or 12 years. Can't find a drive ratio buffer module for a '97 GMC to get the speedometer working again, you might be SOL.
Don't get me started on "engineered obsolescence", "engineered failure", lack of serviceability. GM 4.3, 5.0, 5.7, and 7.4 litre intake gaskets make me want to cuss out an engineer, and having to remove the whole cab to do extensive repairs to a Ford SD, with a 6.4L diesel make me want to beat one until I'm satisfied.
I should be happy though. That stuff keeps me busy...
