Sending unit is TTA only. Fuel tank is all F-body with 1LE. Those are hard to come by IMO. Now I did some checking and I did come up with a part number for the sending unit that was listed for a TTA with 3.8 7 code for export useage WITHOUT 1LE(I thought all TTA's were 1LE) and it was the same unit used in the TPI V-8 cars without 1LE so you know you can use a standard GTA tank and sending unit if you get in a jam. The standard tank has a plastic tray it is just not as elaberate as the 1LE piece.
