OK, permit me to play "devil's advocate" for a moment...
Even if you can find replacement parts NOW, what's going to happen in ten or fifteen years when you want to freshen up that Pacer front end?
Let's face it... there weren't a lot of Pacers made to begin with, even fewer are still in the junk yards, and I can understand why automotive aftermarket parts makers might drop those Pacer replacements.
How wise it is to "upgrade" your truck with something that is already obsolete and difficult to service?
Food for thought.
