Mine only has the long bolt on the fromt passanger side. That one goes through both parts of the frame. Drivers side of frame is only drilled on top. 1-9/16 worked perfect on my washers. Only thing I can say is if you pre drill the holes use a tiny bit because the fostner bit dosent like a pilot hole. Mine walked around pretty bad but then again i was using a cordless drill and just kinda winged it with a pre drilled hole that it chased around and made a few too big.
