355 interior Spider boot fastener locations

I'm having a new boot made for my "96 355 Spider. Besides the outer 2 fasteners near the doors, the '96 and earlier boots had a single fastener in the center of the boot behind the seats that snaps into the male post on the top of the convertible top hydraulic cover. All the boots from '97 and on replaced the single fastener with 2 fasteners in the boot behind the seats. I want my new boot to have the 2 fasteners like the later models. My question is exactly where are their male counterparts located? I am guessing they are screwed into the sloping top edges of the 2 ECU covers, one behind the passenger's seat and the other behind the driver's seat. Although I've never seen them in person, I don't think they are screwed into the vertical faces of these covers. I am guessing they are on the top sloping edges instead. Can anyone confirm this for me? Some photos of each cover to see exactly where they are would be very helpful.

 

Interesting Bob. I thought it was in '97 that Ferrari changed from 1 to 2 fasteners but clearly I'm wrong. Maybe '98's started this or, perhaps somewhere in the '97 model year, some came with 1 and some with 2 from then on.

I've seen several boots with 2 fasteners instead of 1, just never a car's interior to see where on the ECU covers they actually go. I like the 2 much better because it holds the boot tighter and prevents it from flapping in the wind at highway speeds. This will be especially beneficial for me since I'm having my boot made with an access flap to get at the glove box when the boot's in place.

You may already know this but there is also a single hidden snap on the exterior side located at the center of the engine bay. It is a regular snap as opposed to the Tenax fasteners used elsewhere. Its black instead of Chrome and, although its exposed with the boot off, its not very noticeable because of its low profile and black color. The boot has its female counterpart on the liner side fastened through a separate leather tab to conceal it from the exterior leather side. With the boot on, it can't be seen at all and you would never know its there.

Rumor has it that Ferrari found that the boots started to lift and vibrate at high speeds. Pininferrina didn't want to see another exposed chrome fastener there so this was the solution. I had my boot made with this hidden snap. Works great and holds the boot in place better.

As to the question Tom asked, Tenax fasteners are available from Eagle Day, their North American distributer. There are several types so be sure you pick the correct one to mate with the male posts (they are not all compatible). You want the German type with the large heads. They are available in both Chrome or black at about $5.00 each. Stock is chrome.

So, anyone have pics of a '97 or later car with the 2 fastener locations in the ECU covers?

 

Mark,

Do the fasteners on your car hit the seats when they are all the way back? Wouldn't want to accidentally damage the leather on the seat backs. Also, with the boot in place, since its hemmed edge is below the Tenax fasteners, it appears as though this would make the boot bunch up as it goes over the top of the leather covered hydraulic cover. True? Could you take a photo of your boot in place to see how all this comes together?

Not having seen anything, this is why I thought the fasteners would be on the sloped surface of the ECU covers instead of the vertical faces. It appears this wouldn't interfere with the seats and looks like it would allow the boot to pass over the top hydraulic cover with little or no bunching. But it might also make the boot fit too loose and still flap at speed. Anyway, a picture is worth a thousand words....I think someone said that somewhere.
