Does anyone know the exact bolt size for the PCM to secure it to the bracket on the firewall? It has 4 and apparently when the tech changed my plugs a few years ago, one was lost. I know it's metric. I called a Ford Dealer but they gave me the incorrect size-way too small. Thanks

Are the other bolts the same size?

FrozenTundraGuy

Yes. they appear to be the same size

I was thinking n maybe remove one and see what that size is.

Do you really need the 4th bolt? Seems 3 would hold just fine.

OK, the size is M6 X 1.0 Coarse and the length is 40. the original one is a bit longer but this fits fine. I also used a flange bolt, as the OEM had a separate washer which I didn't want to fool with. Removed battery, installed bolt and done.
