Testarossa under hood/grill detail

Hi all. I am attempting to correct some hardware under the front hood of my Testarossa and I can’t seem to track any pictures that show this detail. I am specifically looking for a picture of the rivet that attaches the front bellows to the bumper intakes from the grill. At least I think they were rivets. If someone has a picture of a factory setup of the inside of the intake and the bellows side under the hood, it would really help me out.
Thanks!

 

Hi Vincenzo. I can take a picture of that area and post it tomorrow. I see how my request is kind of confusing. The part I am referring to is 61491400 and how it is attached to the front bumper. It should be the same for all 85 to 91 Testarossas. Thanks for clarifying.

 

That does help, Vincenzo. Thank you for taking those photos. It appears that these are blind rivets with a small washer on the rubber side. Does that seem correct? I couldn’t see the face that is inside the inlet, though. Any chance of getting a picture of those just so I can estimate the size? Thanks again

 

No need to take the grill out. I see where and how they attach now. Thanks again Vincenzo.
