I pasted my Google Adwords Conversion Tracking code into a new file I created
/includes/modules/pages/checkout_success/jscript_google_purchase.php

it is now showing up on the order confirmation page, but it is in the header and needs to be right above </body>

How do I fix that

I am not sure what version of zen cart I have
in the
/zc_installFOLDER/sql
directory I see mention of an upgrade file to 136
