4k rear spoiler

[Mike Victor <victmi00@dons.ac.usfca.edu>]

I am considering adding a rear spoiler (a la quattro) to the trunk of my 
86 4000 cs (NOT quattro). Is there drilling involved and is this 
advisable? I called three dealers here in San Francisco and was given the 
outrageous prices of anywhere between $594 and $673 for the rear spoiler. 
A used one in Sacramento is running $75. Both come primed in need of a 
paint job. Is anybody faimilar with this procedure? Any advice?

Thanks in advance
