Mine has what you describe for the negative side, and then a triple spade
terminal with individual connectors for the + side.

but the terminal connectors are attached to the coil on studs!  That's what
I was referring to, should have been more clear.  On my coil, the + side
stud turned out to have an 8mm nut.  I didn't measure the stud itself, but
the ring terminal I had lying around worked fine.  (I realize that using
spade terminal adapters might have been a cleaner solution... at least I
didn't use a wire tap!)
