    Pipe-to-manifold is sealed by a donut bushing with a stainless ring inside. The ring on my original fits nicely into the manifold and mikes out at 2.375" OD. The replacement part (Auto Zone), which comes in a bag indicating it is for 83-96 350 CID (seems right), mikes at 2.500 and does not fit. Manifold is original.
    Auto Zone's computer calls out either the 2.5" (which is too big) or a 2-3/32" (which is too small). Any ideas on a source & part number for the correct donut?
    Thanks,
    Jim

    the metal ring is a tight fit. I just replaced mine this morning and I had to tap it into place.

    I too had to tap mine ever so slightly into place. The guy at Advance Auto had two different sizes listed, and in stock. I brought with me one old donut to match em up:applaud:. MMM donutssssss.
