Where are some good places to list my 914/6 for sale?

The project has stalled, and it just needs to be put back together.

9146art,

Hopefully you've sold the 914 by now, but if now, I would suggest visiting a couple of the 914-specific bulletin boards:

www.914club.com
www.pelicanparts.com

Both have for-sale postings that are visited by numerous 914 owners and lovers. And 6's are among the most desireable.
