Trying to remove the brake drums from the rear of a 1986 Isuzu Trooper, 2.3L Gas, Manual Transmission. According to the Haynes manual to remove the drums, it states...

"Remove the brake drum attaching screws and pull the drum off the axel flange."

I can only find 1 screw which is located between two studs on the face of the drum. The statement says screws plural, so where is/are the other screw(s)? So far the drum is not budging and I'd like to make sure I didn't miss any screws before going further.

Thanks.
