A program called GooManager lets you access download files in repos kept for Android developers. It should be on your device already; if it isn't get it from the Play Store.
Open GooManager and choose "Browse compatible ROMs". Or Browse all files will work too.
Then navigate "TeamAndroid" / Nexus7 / AOSP / Grouper. There you will see the last several ROM downloads, including the 0210 file. Click on the file and you will be asked to download it.
I believe Sparks said the source patches were not being sent quickly, so not sure if you'll be fixed but it is worth a shot.
