I had issues getting the U-Joints off and brought it to a machine shop. After several hours of heat and enough pounding to numb my arms I handed it over to someone else. He had one hell of a time with it as well...but its done.

The problem is I never marked the front/back on it and since the machine shop removed the U-joint for me I dont want to put it together wrong.

Which end is which???

Thanks.
