air filter cover nuts

I used Nylon nuts because the correct ones vibrate themselves off the car. Function over Style, for me.

 

It can vary a bit by year, but typically for a carb GTB you want the domed version, not the flat ones. IMPORTANT, get the thick black rubber fender washers that go with them. They prevent them from coming loose like what happened to Yelcab. Don't reuse the old washers with new nuts. The hard old rubber will transmit the vibration through and cause them to work loose more easily. Soft new ones allow you to tighten them better.

 

I think I still have a couple extra of the non-domed top nuts if you need them. I'll look for them tonight, shoot me a PM if you want them.

 

Actually I have four of the domed nuts if you'd like them. Sorry I remembered wrong but I did find them!

 

Can I jump in here? I need domed nuts, anodized or chrome?

I have a 79. I need 4 domed nuts. Not chrome. Thanks, Steve

 

Believe it or not, I had luck finding these at an independent mechanic's shop... I had my car in for some minor checkup-type thing, and as we were standing by the back of my car (engine cover open), I said, "Oh....and do you know where I can find *those* online," pointing to the knurled thumbnuts. He laughs, walks about 4 steps to a little chest of drawers on his workbench, pulls open a drawer full of 'em.

"Here," he said.


SWEET!

 

Philip started the thread and PM'd me earlier about the nuts. It looks like they will work for his car so if he wants them he gets first shot. If not I'll let you know Bill. Just so you guys know though I found them at Ferrari UK when I bought them. I don't know if they have more in stock though.

Edit: I'm not sure what the finish is on these, they are silver but it's not chrome. Looks like maybe a zinc plating or something.

 

Looking through eBay I happened across this listing.....http://cgi.ebay.com/ebaymotors/Air-Box-Nut-Grommett-Set-For-all-75-79-Ferrari-308_W0QQitemZ350023575725QQihZ022QQcategoryZ42604QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Looks like a pretty good deal but somebody needs to take these off my hands!

 

Jdubbya or TRutlands are in my future. Let me know

 

try Superformance, they sell them. I bought them to and they are just as original as can be.

 

As mentioned, T. Rutlands, Superformance and Ferrari UK are good sources. Here's a picture of my cover (1976 GTB). The nuts are the flat-top type:

Check your PM. I'll be heading in your direction tomorrow and could drop them off.

 

Anyone have a size for these? Looks like a common item with many options on Amazon including stainless steel etc. Thanks

 

Image Unavailable, Please Login Super performance still sell them and the rubber washers under them .

 

My ‘79 Euro GTB came with two different designs. Have no idea which is correct nor to what application the other design belongs; if even for a Ferrari. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
