Are the '88 original GM hydraulic mounts noticeably different in appearance than a standard mount?

I have the GT engine/trans. cradle out for an auto. trans. swap, and figured it would be a good time to inspect all the mounts.
The right front engine mount is still solid and in one piece, but does not look much different than another solid mount. Maybe it has been changed already in the past. I don't know.
I have only owned the car for a couple of years, and it has been sitting, ready for a trans. swap, all that time.

Any tell-tale signs to determine if it is a hydraulic mount?

Thanks for the help.

The Hydraulic mount looks different than the solid mounts, but an aftermarket solid mount has been made that looks like the hydraulic mount.... There are pictures on the Fiero store website.

Right, I saw those.
But could not see much detail in the photo of the hydraulic part.

I am betting mine is a solid mount, from the looks this one I pulled off today.
