Harbor Freight Engine Stand

I am sure someone else has one of these. I hope it is not just me but mine will not work for a 360. The Arms that are bolted to the plate on the stand are not long enough to reach the Back of the Engine. I can get the 2 Upper arms to attach but not the bottoms. What do you guys suggest i do? Should i not use the arms and maybe use a Thick steel plate?
I've never seen a stand that wouldn't reach. Not to challenge your skills, but I would look again for additional adjustment. Post a picture? Is the plate turned upside down?
