internal to external slave

While installing my conversion I discovered that my new bellhousing(from a 94XJ) does not have anything for the pivot arm to ride on. There is a hole in the bell housing across from the slave opening that I assume should have some sort of pivot ball in it. Does anyone know if this part is available, and maby a part number. If anyone has a picture of one I may be able to fab the part myself.
Thanks in advance for any help.
