Attention: TDR Forum Junkies 
Having a clutch put in next Mon. and I am having the rear main seal done while the transmission is out, the current one seems to be seeping a little. Picked up the seal and a gasket for the cover thats around it, well I call it a cover.
The rear main seal P#- 4089342
The gasket P#- 3938159
Willie over at Cummins Southern Plains is good with these parts not saying he's wrong just wanted to double check. He told me that all the 5. 9 ISB's share the same part number as far as the rear seal is concerned. Would hate to get this thing all tore apart and the shop tells me that the seal is not the right one, you know.
