Rick:
You are so lucky being near Jegs...
Although, on the other hand, I probably would blow lots of bucks if I were close to them.
I found a real nice fluid pump (plunger type) at Sears that fits into an
oil bottle. This has been the best thing to pump heavy
oil into the differential as well as the trannie. I do not remember the part number from Sears.
Cheers
