The hole in the motor mount is 1.900" and the mount is .600" thick. The hole in the crossmember is for a 3" x5/8" bolt. I don't have any in stock. I have about a half a dozen motors in the warehouse, but none of them have the pad stuck to the mount. That is where I got the thickness of the engine mount. I would consider this necessary to get the correct crush on the insulator. If you know an International parts man, tell him to pull a front mount for XC086003. I measured the mount on the engine that came out of that truck. If you don't have a good source for IH, I can give you the name of parts people in San Antonio that will help you if you mention my name.
