It looks like the rear main support bearing on the main shaft.
RBT doesn't have this bearing?
The two most common bearings needed for this transmission and any transmission are going to be the input shaft front and rear bearings.
If they are no longer being made or there are no substitutes that is another major blow to this car.
The only way to get one will be to take one from another transmission. Wait, let me call the juke yard...yeh right!
