Rhodes Suitcase Amp Feet/Bumper Instillation Help

[tuttlerecall]

I was hoping that someone with a late model (flat top) 88 Key Rhodes Suitcase could please post a pic for me of where the feet go on the bottom of the amp?  I spoke with a local tech and he said not to install them on the corners like on the keyboard but rather they should go next to the corners.  I removed the tolex but the bottom was so shot there were no screw holes to mark where they should be installed.
