Default Metric or Standard?

Anyone know if the 4 bolts that hold the Harmon Karden head unit in a 2012 Ultra are metric or standard? Service manual doesn't say.

Thanks!

David

I believe the hardware retaining the head unit is 1/4 20 Allen head screw

Those head unit screws do seem to be an odd length though. I had to replace one of mine that fell down into who knows where and I found some in stainless steel at the hardware store but some were too long and some were too short, so I just got the long ones and cut one to match the length of the other screws.
