Drop in point for my old Diebold Safe

[hd54kh]

Hi, I had opened this safe many years ago and have not used it for so long I lost all my info. So I was able to read the wheels It has three combination wheels and the drive wheel. It is in such a tight spot it is tough to keep dialing it to find the correct drop in. So maybe a little guidance might help me out. I drilled it open upward at the 6:00 position, easily read the 4 gates but now just need the drop in. I hope the couple of pictures might help.

The safe is 20"W x 20"D x 30"H and painted an ugly green/yellow. Inside has a locking door and inside that are 2 locking draws a couple open shelves on the left and the right 2/3s is just open. Interior is in fairly good shape. I have all the keys.

Thanks in advance - Terry
