Antenna for 87 5kcstq

[Mark Trank <mtrank%acva@mail.co.albemarle.va.us>]

Having just acquired my first quattro (can't believe I'm secretly hoping 
for snow and its April in sunny central Virginia!!) I'm going through the 
car to determine what needs repair/attention.  Among other items, radio 
antenna is cracked and needs replacement.  Any suggestions on parts 
sources out there?

TIA,  
Mark
