Lead Pipe - Now what?

[Lunker]

Ripped out the old toilet and turns out the old flange wasn't even attached to the floor. It had a wax ring under and above it... it didn't leak so I guess it worked, oh well.

The drain pipe is made out of lead, and top is level with the floor.

The floor is concrete.

Went to plumbing supply house and they sold me a brass flange and a lead pipe extension.

What the heck do I do now? How do I get a tight seal between the existing lead drain and the extension? I can't just jam it in there I need a seal between the two pipes somehow, right?

Thanks, yeah I posted my question here first but it looked like I would have a better chance of getting a response on the other tread, so I posted there as well...

Again thanks!
