Rear main seal issues
Rear main seal issues So I'm replacing the main seal in my 5.3 pull out cause I accidently tore it when installing the rear cover plate. The motor is somewhere between a 00-03 and I'm having troubles finding a seal that matches the stock seal.

Has anyone else replaced a rear main seal on a GENIII Ls engine and had this issue or is it just me? the Federal Mogul seal number was cross referenced with the stock seal and the guy at O'reillys gave me it. I was leary do to the fact its no where near close to the same width as the stock seal, so I went to Napa and they gave me the SKF seal and its the closest width to the stock seal but the material and construction of it greatly differs and that kinda worries me. I don't wanna pull the motor after installing it cause of this.
