I bought a ICP from international with the #1812818c93. Every where else I look its a diferent number and when you google the number I have, nothing of any substance is available. I called a couple of guys and they cant reference that number anywhere. I talked to the guys at the international dealer I bought it from and they said it was the same as 1807329C92 but another dealer said different. Im a bit confused. Different answers and little to no info using my googlefu. Anybody have an answer?

 

My spare ICP is the 1807329C92 which is interchangeable with Ford P/N F6TZ-9F838-A.

The older 1807329C91 were the OE style with the reduced base, the C92's have a large base for easier removal. From what I find the one you have may be for a 466, butthey may very well be interchangeable.
