Email unsubscribe AND preference center

Hey everyone,

We want our email footer to look like this:

This Email was sent to ....

Manage Subscriptions | Unsubscribe

We have created a subscription center to point the Manage Preferences to, and we want to leave unsubscribe pointing to the original unsubscribe.

Original HTML was:

<p><font face="Verdana" size="1">This email was sent to {{lead.Email Address}}. If you no longer wish to receive these emails you may <a href="%mkt_opt_out_prefix%UnsubscribePage.html?mkt_unsubscribe=1&mkt_tok=##MKT_TOK##">unsubscribe</a> at any time. </font> </p>

Want to update to:

<p><font face="Verdana" size="1">This email was sent to {{lead.Email Address}}.</font></p>

<p><font face="Verdana" size="1"><a href=“FULL PAGE URL”>Manage Subscriptions</a> |  <a href="%mkt_opt_out_prefix%UnsubscribePage.html?mkt_unsubscribe=1&mkt_tok=##MKT_TOK##">Unsubscribe</a></font></p>

I am getting a 404 page not found error whenever I test. Any ideas?
