repairing clay sewer pipe

[Mike Salazar]

I need to replace a two foot section of my clay sewer pipe with some PVC pipe. My question is how do I connect the PVC to the clay pipe, do I use some sort of plumbing glue, rubber gasket, metal tightener or what, I've never done this before. Also should the PVC pipe have a smaller, larger, or equal diameter to the clay pipe. Thanks so much for any input!!!
