NES CARTRIDGE to AV Famicom

[Europemodder]

I try to find best 72pin NES cartridge  to Famicom 60 PIN GAME CONVERTER, but sellers told, thats adapters NOT COMPATIBLE w/AV Famicom.

There is one example:

I believe that the adapters are too short to AV Famicom, so is there any ~ 30$ adapters to AV model?

This is not what I like to use, because it does not have any plastic support around adapter.
