Connecting WC to a lead soil pipe

[amwater]

Hello, I'm new to forum so I thought I'd get stuck in with this: I had a call out for a leaking WC waste. Its a late nineties close coupled, connected to a lead soil pipe which leads to a asbestos stack. Its been seriously bodged with silicone etc and they've glued a 'half moon' section of plastic pipe to underneath??. I was thinking about cutting the lead back and fitting a flexi pan connector but I'm worried about there being no standard sizes for lead. Has anyone any suggestions for connecting up to lead.

There are two sizes of lead 3 1/2" and 4" get a multikwik extension and pan connector to suit,

Thanks for that, I'll go ahead with the 3 1/2" extension with confidence. The pipe gradient runs back slightly towards the pan so that'll need freeing up and bending in the right direction.
