Sounds like you got one tempered and one laminated?
Tempered glass will literally 'explode' unlike laminated that simply cracks.
Easiest way to tell is to look at the edge of the glass.
Laminated will have 3 layers (2 glass,1 interlayer) and tempered only one.

Buying glass for your A.D seems to be a bit of a minefield.
Quality and fit seems to vary wildly.
I'm fortunate and do this for a living,so if it don't fit I know who to blame! grin
I hope you got it sorted.
