: The pipe is buried under the new finished floor. Then it connects to a 3" pvc elbow which is street on one side. The street part slides in the toilet flange BUT is about 2 inches too tall. If I take an inch off the street elbow and the toilet flange I am still up an inch too high.

Allen,
They make a 45 degree angle closet flange which should work. If you use the 45 degree angle flange with a street 45, it may work.
Sorry, they don't have a picture of it.
