Default Rear Main Seal

I am doing the rear main seal in my 92 4.0 automatic and am wondering what exactly I need and where the best place to buy it is. Any input is greatly appreciated. Never done this before but heard it's not that difficult and I am pretty mechanically inclined.

Nearest parts stores. Get the FelPro one piece oil pan gasket and the FelPro dual lip rear main seal.

Clean block real good and use a decent gasket adhesive (i use HiTack97, right stuff will work in a pinch) and have someone help you place the gasket up and install the bolts in. Let it setup overnight if you can.

Gluing the gasket to the block makes it much easier to place the pan back up without the seal moving on ya.

Make absolutely certain its not the valve cover or oil filter adapter. I wasted a day replacing that stupid seal, it was still leaking afterward. My back three bolts on the cover were finger loose all the others were super tight.

Yea I actually just replaced my valve cover gasket and did an oil change about a month ago and it seemed to be fine.
