Hello,
I'm not sure if this is on topic for this newsgroup, but I have
been doing some FM dx'ing lately with my car stereo. The receiver actually
is very sensitive and selective. However, I want to use an external antenna
with it. Is it possible to attach an external beam antenna to the back of a
car stereo receiver?

Sure, just use the antenna connector.
It's usually a "motorola" connector.

Got a need to read Bar codes? http://www.barcodechip.com
Bi-directional read of UPC-A, UPC-E, EAN-8, EAN-13, JAN, and Bookland, with
two or five digit supplemental codes, in an 8 pin chip, with NO external
parts.

Yes, but aside from the connector adapter needed, there is another
consideration, overload. The auto receiver was designed for optimum
performance using a short rod antenna. The yagi is going to present much
stronger signals to the front end of the radio, and you may find that the
front end or mixer overloads, and you hear fewer wanted weak signals, and a
lot more intermodulation products from the strong signals. To sort them
out, you will need an adjustable attenuator to balance the amount of energy
you pump into the receiver against where it overloads.
Good luck; BTW RatShack has the adapter(s) you need, but the attenuator will
have to be found somewhere like a ham swapfest, unless you want to use a
bunch of fixed attenuators and connect/disconnect them as needed.

Radio Shack also sells an attenuator for this purpose.

For what it's worth, a carbon pot of something like 200R will work
perfectly well as a variable 'signal level adjuster' - no real need for
a matched attenuator.
