Decent Replacement Speakers for 5k

[M Connors <mconnor@frontiernet.net>]

Attention Audi Audio officianados
    Can anyone in Audiland recommend some decent replacement speakers
for a stock '87  5Kcstq?  I am looking to replace the original dash,
front door and rear "trunk" speakers on my car but want to retain the
original door grillwork and factory look in the car.  My speakers have
seen better days.  Also, if anyone knows, where is a good source for
these via Mail-Order.

Thanks in advance!
Mark
