Am I being a pack rat?

[JDmills]

I am sending the 300D parts car to the scrap yard next week, and would like to pull parts that may come in handy in the future for my daily driver.

I am mostly thinking in terms of electrical/climate control stuff. (the motor and trans/rear end are on the way out today.

So far my self genereated list is:

windsheld wiper motor/assembely
gages
all switches
blower motor
fuses
Brake booster

What about the relay switches? do they fail, or am I wasting my time thinking of all this stuff.
Driveshaft?
A/C stuff?

May be I am being a pack rat, but they dont make this stuff any more, and I usually regret tossing some thing out only to have and pay $$ for it later.
