Air Cleaner Housing/Intake Hat O-ring part number

[Fordtruckfan89]

The Air Cleaner to intake manifold O-ring on my 89 IDI f250 is cracked and will not stay in the groove or channel on the air cleaner when its taken off. Most of the carb gaskets I've found people use to seal the intake on turbocharged IDI's, such as the felpro 60038 are flat, and not oil resistant. The Stock Naturally aspirated IDI Air Cleaner Housing requires a thick square cut O-ring. I understand years ago a member on here was selling O-rings made by Caterpillar that fit the air cleaner. Does anyone here have the part number for that O-ring? Mcmaster-Carr sells Buna-N O-rings in a pack of 5, but that seems excessive since they last for so many years.

Any advice or help is greatly Appreciated

Thanks
