Rebuilt A 833 front oil leak

Oil leaks from the front snout see arrow. This trans was rebuilt buy a Transmission guy I have used before and have had no problems with but he's moved out of state. This rebuilt 4spd sat for about 5 years before the car was ready for it. While on the transmission jack and readied for installation I filled it with oil, while I'm pumping away and pretty sure I had exceeded the unit's capacity with no oil exiting the fill hole I saw a flow of oil coming from the end of the front collar/snout see arrow in pic. ( I did notice the tranny was tilted fwd slightly).

It's important to understand that initially I installed the 4spd (with no clutch OR PILOT BEARING) only to support the engine since the plan at that time was to break in the engine and check things out without driving it then tear it down for paint. After installation I topped off the trans oil until it ran out of the filler hole. Over the next several months I ran the engine many times and had no leaks transmission or otherwise. No pilot bushing means no input shaft turning during these engine runs and with full transmission oil capacity I don't think a flange or plug leak developed instantly after driving to confuse this issue.

Then my plan changed, I really wanted to drive the car so I checked the Transmission oil, pulled the trans. back, installed a pilot bushing and clutch and reinstalled the 4spd. and have many trips on the car each time producing a leak when parked. Visually when under the car, the leak can be seen at the Bell/Trans interface. Interior of bell and clutch are dry.

I've never rebuilt a 4 spd, so did my guy omit a seal? if he did maybe it's dried out after sitting 5 years? If oil is creeping out of the snout how can the clutch and bell be dry? If you all are able to easily identify the problem, what is the fix?

Much Thanks
