Just contacted Courtessy Nissan and they say the are out of stock! Anyone has any clues of where to find these 3 seals or should i just purchase the above mentioned kn filter and forget about the seals? Will this provide the same effect?

240z rubber parts makes and sells them. I inquired recently about the "out of stock" message and he said he would make them upon order.

Steve Nixon makes and sells them along with virtually ever other non-available rubber part for the restoration of 240Z cars.
These gaskets are not cheap but they are exact reproductions of original gaskets. They fit and function perfectly and will last a very long time.

I documented the use of Steve's gaskets in this thread:

Quite expensive indeed US$150??????

Maybe I should have asked if you are "restoring the car" or just trying to "make do".

If the latter is the case, then buy some foam weatherstrip from a hardware store,  as many threads on this topic have suggested, and be done with it.

Hand-made gaskets aren't cheap. The factory parts costs how much?

Anytime an individual invests the molding / fabrication / design dollars to reproduce something like this, given the low volume, the price is going to be high. Each item sold must contribute to cost recovery (direct and R&D) and when volumes are low, the rate is high- not to mention factoring in a provision for profit.

 

I recently had a tool made to be used in a shop press to allow for the original mustache bar bushing sleeves to be bent over the mustache bar eyelets in the right original shape...without tearing the sleeve. I had several extra tools made but could likely never sell them at a price folks would think reasonable. It is just how it is with low volume.

 

Personally, I am just thrilled that 240zrubber is around and some of the rubber items they provide are available.

it's often difficult to understand actual production costs in low-volume delivery. the tooling for a ball-point pen can run into the heavy 6 figures, yet production in the millions makes the unit cost so negligible that most people won't bend down to pick one up on the street. make 10 custom ball-point pens from scratch wand they would be hundreds of dollars each (at best). 

 

high quality, low-volume reproductions are rarely a money-maker for anyone, they are most often a labor of love where the fabricator simply wants to make a part that is otherwise unavailable and once the tooling is made the parts are offered to other like-minded folks as a service. i've produced a few parts and offered them to forum friends (in the motorcycle world) and run into the same issue.
