456 M trunk lid gasket

Try contacting this outfit. They make custom molded rubber and it's likely they can help you.

 

I read somewhere, perhaps it was the sticky at the top, a Nissan Altima trunk gasket, was quite similar, take a look at that sticky...my memory doesn't serve me as well as it once did

Update found it post 144 in sticky above, was for 550/575
May be compatible with 456, may want to look at this further

 

As others have already indicated, a lot of types of car body rubbers can be obtained from rubber supply sources, ebay, etc. You just need to identify the correct profile and find a source.

 

I paid about $250 from Eurospares for the factory gasket.

 

Happend to me too dragging a suitcase out of the back once- I bit the bullet & replaced it

Now I'm ultra careful...

 

The rubber is sold by the foot by T Rutlands and GT Car Parts, 2 of the oldest and most experienced Ferrari parts suppliers on the planet.

 

I have a 1997 456GT with a trunk weatherstrip in need of replacement.

On the heels of your suggestion, I obtained a brand new NISSAN 848303TA0B GENUINE OEM WEATHERSTRIP on eBay for $35. Hey, I thought, if it doesn't work on my 456 I can certainly take the hit.

Once it arrived I noticed immediately that the section of the Nissan item isn't the same as that of the 456GT weatherstrip. In fact, it looks quite a bit different, though the height is identical.

Just for kicks, I removed the old strip and installed the Nissan one and... it works! Not only does the lid close producing a solid sound that leaves no doubt as to the fact that lid and seal make full contact, but it also passed the water hose test. I washed the car and once I was done the trunk was completely dry, with clear evidence that the water was running down around the outer edge of the strip.

To summarize: the NISSAN 848303TA0B weatherstrip is a suitable replacement for the 456GT OEM trunk strip. Don't let the different section design fool you: it works.

 

Awesome. Thanks for experimenting!

 

You consider reposting the summary in the sticky that cross-references parts. Most useful.

 

Done!
