Where is all common leak sources possible on a 65 904?

Yes I just noticed on EBAY Pat Blais has all the seals I didn't even know this thing had. I looked again and it appears that most if not all the fluid is concentrated in the parking cable area. I see fluid on the inspection screw for the park cable release hole. The allen head screw. I put a new oem gasket on that park cable cover when I reinstalled the cable. I remember installing that park cable and it took me forever to figure the theory behind how it does what it does but eventually I got it to work right. I didn't want to fool with it again but it's keeping me from driving the car.
