Looking for info on which version of GAPPS i should use for Shield TV 16GB.

I recently flashed Zulu99's Full Android 1.8 rom on my 16gb shield tv and it loads 5.1 just fine, but after flashing any Gapps i get the same "Unfortunately Google Play services has stopped." message at the welcome screen and after skipping setup and trying to add an account or signing into google apps i get the same message over and over again. Should i use a certain Gapps package for the rom?
