Broken turntable support

I have an Emerson Model AR550 microwave (I know it's old but still cooks!!)

Anyway---- the three legged support that the glass plate rests on has broken into two pieces, I haven't been able to find another one online and was wondering if I could super glue the pieces back together without having to worry about any fumes or danger from the glue being nuked??

I only use the oven for popcorn and to heat up leftovers -- no really long timed cooking.
