How to rebuild a package with full source upload?

["With No Name" <withnoname@tdwave.net>]

Hello,

I was searching the Debian website forward and back but I do not more find
the page, where it was written.

I mean, I have the

package_1.2.3-4.dsc
package_1.2.3-4.diff
package_1.2.3.tar.gz

from the last version of a debian package which was removed and now I
rebuild it for e.g. squeeze and name it

package_1.2.3-5squeeze1.dsc
package_1.2.3-5squeeze1.diff
package_1.2.3-5squeeze1.deb

in the changes/upload file I have only those three files, but I need the

package_1.2.3.tar.gz

too.  How do I do this?

Thanks in advance
