Guys, removed all accessories to bumper including plastic cap... Tried removing each sides 3 bolts to the plate where they mount to like a "sleeve" that also slides into the frame, also secured by a bolt on bottom of each frame rail... Was I supposed to take different part of bumper off first, then try removing those "sleeve" mounts once body is off frame so I can get to the bolt nuts from the top of the frame? Confusing. Thx
