1991 200 tqa center muffler

[Tom Donohue]

For whatever reason, unable to access Marketplace, so hope to put this 
question out to the list...I have a menagerie of '91 200 tqa's that I am in 
the process of reducing.  Have a buyer interested in my Glacier Blue 
version.  Need a center muffler.  My local sources say it's dealer-only, 
which appears to be + $300 just for the part.  Anyone have a good idea for 
alternatives at a much more reasonable price?  I'm in Western MA and travel 
the eastern seaboard to Phila or a bit further south regularly...also OK 
with travel to Albany, NY, Hartford, CT, Bennington, Vt or that general 
perimeter to chase parts.  Any thoughts will be welcome, especially with the 
weak price offers I've been getting for my Avants, despite their pedigree 
and scarcity???  Thanks.  Tom Donohue
