Part number needed
Part number
Try "amayama.com.au" then select "parts catalogues", then select your car....then you will find something similar to the link below, glass from an io but the H76W chassis serie.
New may not be the best as they are expensive, a wrecking yard could be another option, or even cut a plate of aluminium checker plate....
I hope that you get it sorted...

Happy io
Without a bit more info I
Without a bit more info I can't find it for you sorry, but going through mitsubishi.epc-data.com/pajero_io/ should be all you need.
I will guess finding the part number wil be the easy part, the glass on the other hand...good luck.
