I've never messed with a Sazco, the glazed interior would have me concerned. The Kamados I have refurbished have been unglazed and Hercules High Temp Furnace cement and JB Weld seem to work the best. Not very well on a BGE glazed surface.
Also never used refractory cement, so no help with that either. Possibly a pottery supply will be able to give you a better idea of what might work.
You might want to take it to a Big Green Egg dealer and see if the firebox from a Large will fit in it.
