Connecting into soil pipe with new plastic stack

[ddma]

I am in the process of replacing the cast iron stack at the side of our house with a new plastic system.
The side path is being replaced at the same time and while breaking the concrete it revealed that the upper lip of the clay bend set in the ground was cracked and broken away.
What is the best way to connect the new plastic soil pipe ? Is there a fitting anyone knows of or I am going to have to get my spade out and start digging with a view to changing the bend completely ?
I've attached a nice photo if it helps explain my dilema. Help required urgently as I'm tackling tshis one this weekend.

I did a similar job recently, I used a McAlpine fitting, female is the plastic and male end goes into clay. A good builders/plumbing merchant will stock it.

Thanks Outlaw.
Do you mean something like this ? How does it seal, do I cement or silicon ?

Thats the bugger
Push it in with some silicone lubricant on the rubbery bit on the male end, then when you have cut your stack pipe to length (measure what will be in the fitting too) chamfer the end of the cut pipe and lube it up too, it will just slide in with little or no force if the end is prepared right.
