Injector Insert Help???

[TAHayes302 at cs.com]

Hello Audi Enthusiasts:
I have a quick question about fuel injector inserts on my '86 4000q.  My 
Bentley shows that the plastic insert has been updated to a new two piece 
metal unit.  I was just in the process of pulling my fuel injectors and 
noticed that my Bosch replacements look different than the originals.  They 
have 2 o-rings instead of 1.  From reading between the lines it looks like my 
only alternative is to install the metal injector inserts.  If that is the 
case will these 15 yr. old plastic inserts disintegrate when I try to unscrew 
them.  Any insight will be greatly appreciated.
Thanks,
Todd Hayes
