Where to get head stud bushing?

Anyone know where to get the flanged bushing (sleeve) that go in the head on the bottom row of the head studs for an early Brad fuel head? 1/2" studs. I looked at mcmaster carr and found flanged sleeve bearings that look like it but I dont know what material they're made of (on the head) or if any of these would work?. I also looked on brads site and didnt see anything.

Thanks,
Adam
