Anybody any idea what the thread size is for the holes under the rear crossmember for mounting the military dropplate reinforcing plate, the three underneath the crossmember?

Seems they are 3/8 UNF

I'll have a look, I fitted all this a few years ago. 3/8 or 7/16, I can't remember. They are just plain holes.

Had a look, they look like 1/2". UNF as the heads look to be 3/4 AF. I seem to recall looking at M12 and finding them a bit loose.

They are 3/8UNF threaded holes. When I got the tank mounting bolts I tried one in the hole and it was a perfect fit.

My mistake, I was looking at the bolts through the crossmember for the NATO hitch. While mine has a mil rear crossmember the drop plate is welded to it..
