Anyone have pics of the differences in Catalytic converters?

Trying to determine if the Cats have been replaced on the new 90.

Thanks

The '90-'92 are a single unit, manifold and cat are welded together.
The later years have flanges and can be unbolted.

Are the bolts from the converters easy to see, or are they hidden behind heat shields?
