Yes, post measurements! All of them!
I also suggest you try to sale it on Craigslist as well, though it can be a pain in the ass to deal with spam, scammers and low-ball offers (when I post, I clearly state that offers will not be considered until *after* the bass has been inspected, and I don't bother to reply to emails asking "what's the lowest you'd take?"). I've sold two basses on CL, and both took over a year, but I did get the fair price that I wanted on both sales.
You might want to consider taking it to a good shop to sell on consignment. That's the ultimate hassle-free way to unload a bass. Also, a good luthier can better evaluate the bass' worth and the reality of the market. You'll have to pay a commission, but that will be counter-balanced by the fact that a bass vetted by a reputable shop will fetch a higher price than one sold by an individual.
