Part number and source needed

I need a rear main seal for a 1990 5.0 truck in 2 piece.

the parts stores only sell the 1 piece - I guess no one replaces seal/bearings with the engines in anymore....

No 2 piece rear main seals are listed in the 1990 and later parts catalog. One piece only.

-------------------------------------------------------------------------------------
From the 1980/89 Ford Light Truck Parts Catalog:

1980/89: 2) C9OZ6701A .. Rear Main Seal ~ Rope Type / 6 51/64" long / Cut to Fit.

1980/83: 2) D4FZ6701A .. Rear Main Seal-Split Lip Type / Use before 12/1/1982.

1983/87: 1) E5ZZ6701A .. Rear Main Seal / One Piece / Use after 12/1/1982 thru 2/16/1987.

1987/89: 1) E7ZZ6701A .. Rear Main Seal / One Piece / Use after 2/16/1987.

I'm building a 5.0 for my 94 and wanted to do a two peice. I found that even though a two piece designed for an older 302 may fit a 5.0, its really not designed for a 2 piece. I'm going with the one piece.

I know they only list the 1 piece now (this is the original 90 engine and the other 90 I have sits under a tarp and the OTHER 90 I have is on the engine stand. The problem was, ford built these with 2 piece seals and Id looooooove to change it engine in the truck....

the one I am running right now is gushing oil - 1 qt per tank fillup (I expect the newly cleaned and painted frame/underguts will never rust, but still)

....so I take it that you mean a "cheater" kind of two piece seal was made for servicing the one piece rear seal without removing the flywheel?
