Sorry if I offended, let’s just say that Getrags are available for a lot less dosh than the Trmecs
No offense at all. Just make a separate listing for your item for sale with the price. You are more likely to get some interest that way, it's to your benefit. Unless you do sell transmissions or kits professionally, it would be a posting in the FOR SALE forum. the COMMERCIAL ADVERTISING forum is for those members who are listed as business entities, or when your fellow members find something commercially listed somewhere, such as the initial listing here, a car for sale at a dealer, etc.
There's probably more than a few members who cannot deal with a $6,000 price tag, and yet want a 5-speed. So, post what you have and see what comes of it.
