Do you only want download links or is read-online okay, too? It looks like some sites have taken Gokinjo down as it has been licensed (but who knows when or if it will actually be professionally released in English), but this site still has it up.
The scanlation group who did it appears to no longer be active and their website is gone, but it looks like other places have mirrored it for download as well. Here is a torrent, if you use Bit Torrent. This site has it for download, but the chapters are all up individually and that's 33 chapters, so kind of a pain. The links are working, though; I checked. I also found this post with it uploaded by volume, and six of the seven links still work, so you could download those and then just get the chapters from vol. 3 from the chapter downloads.
