The PAI 631261 Oil Pan Gasket (available via Wofford Truck Parts) is specifically crafted for the Detroit Diesel Series 60 engine family, fitting front- and rear-sump configurations in 12.7L and 14.0L versions. It replaces OEM part numbers 23522279 and 23539104.
With a gasket length of approx. 45.5 in (≈115.6 cm) when laid flat, the gasket is designed to match the oil pan flange on these engines.

Before installation, verify your engine is a Detroit Series 60 (12.7L or 14.0L) and that the original OEM part number matches one of the cross references to ensure correct fit.
