Help with gravely comm 10a front bolt measurement

[Catchneat]

Can anyone close to their comm 10a measure the distance center to center of the front attatchment bolts? I measured it this morning and ran off forgetting my papers, When I got to the shop I cant remember if its 3.5 or 3.75 inches, working on a retro fit thanks. Ed
