Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.

If he is sure that is the problem through testing then you can provide that info he is requesting, you can also go to the board and the part number will be located directly on the board. In terms of the no spark I would check if coil has no park check my 12v pos to it with key on and check for pulse signal when cranking on the neg side of the coil via a test light. But it sounds like he has already narrowed it down to a failed board in which you just need to provide the info he needs to order the correct board.

Thank you!
