Table saw kerf plate required?

I have a B & Q portable table saw Performance Pro CLM1500TSS. I broke the kerf plate or table insert which is an orange plastic plate on each side of the blade and which is flush with the cutting platform. I broke it trying to cut a stool leg lengthwise and so the saw is now not safe to use. I'm sure lots of these were bought about 4 or 5 yrs ago but I cannot get the spare kerf plate from B & Q. Can anyone help me please?

If anyone was disposing of an old similar saw I would very much to hear from them.
