Treadle sewing machine

I just bought a new Janome 712 T sewing machine.  My plan was to put it in place of my old treadle machine.  I ran into some problems of course.  The bolt/ latch things are too widely spaced and too large to fit the holes in the machine.  So now I'm looking for a new top to replace the antique cabinet with and the correct sized bolt/ latch things.  I can use the base part of the treadle machine though.  I wrote to the company that I bought the machine from to see if they have the correct size bolt/ latch things and am waiting to hear back from them.
