I plan on replacing the seal in my truck in the next couple days. Truck in an 01. My question is does anyone have the cummins part # so i can get one from my local dealer or does anyone have a better place in mind that i can get one and get it here soon. I had read somewhere that they ran about $75 and the only thing that the local dealer could find was gonna be over a $120. Thanks for any help in advance.
