The reason I ask is that some people mistakenly believe the weatherstrip is to blame if a bit of water leaks into the cabin when it rains. It's often just that the four drain holes are plugged. When they're clear, a Fiero can be driven in the rain with the sunroof open... and water does not enter the cabin. It's something I do all the time here on the (usually) rainy west coast of BC.
I'll email you the Drain Hole Fix. The document also includes where adhesive is to be applied when removing and replacing the seal. I tried to attach it here, but it's a document, not an image.

Was going to say the same but Patrick addressed it first.

Didn't get a chance to really examine it- I'm not sure that the weatherstrip is sealing well against the glass. I'm aware that there are drain holes but haven't looked at it yet. Heard that applying Castor oil can help revitalize the seal a bit. is that true?

Sure, it's preferential to have the weatherstrip seal against the glass, perhaps more for preventing potential wind noise than water infiltration... but I just want to reemphasize, the rubber weatherstrip seal does not need to seal against the glass to keep water out as long as the four drain holes are free of debris.
I have used castor oil on my sunroof rubber weatherstrip seals... maybe twice in 25 years. I just don't see a real need for it.
So, I need to make 4 holes in the inner corners of this plastic part? (Where the white dot is?)
NO !
Give me a couple minutes to find the proper instructions...
Okay, I found a picture that I "tweaked" and posted years ago which show where the holes are supposed to be located. The earlier years (84-86?) didn't originally have the holes from the factory, but smart owners have added them.
Go Here for instructions if you need to drill the holes... but it's possible you'll find they're already there. In case that link dies, here's a screen grab of the most pertinent info.

Looking more closely at your photos, I can see you've already got at least one hole drilled in the panel, and all four are probably there. Perhaps you'll find one or two that are plugged. Clean all that crap out from beneath the weatherstrip! (A shopvac with a crevice tool should do the job fine while you're holding the weatherstrip back out of the way.)
