90mm cast iron

[gasfit247]

Hi i wonder if any one can help me please ?
I have to connect a toilet waste ie 100 mm into a 90mm lcc cast iron waste .
I can find no adaptors do i have to change the whole stack?
There is a T jct at more or less the right place in the stack
if i could get my pipe to reduce into it.
Thanks

Could ya use a cast iron to plastic adapter like this?

If it is inside use a mcalpine multiqwik extension.

Btw the cast is 3½" not 90mm
