Pricing Used TR6 Parts/seat rails??

["D. Michael Scott" <dms@snip.net>]

Here I am again, trying to figure out the fair going price for used
parts in fair to good condition. Wish there was some kind of parts
reference, other than just looking at catalog/new prices and saying 50%.

Seems hard to price an item that appears to be no longer manufactured.
Any sites on the web for this? And what do you think the fair market
price for either an individual, or a pair (meaning two/left & right), of
fair to good used TR6 seat rails?

Any comments appreciated, D. Michael
