Special female RCA jacks


I'm having a hard time finding a female RCA jack that is suitable for mounting through a thick chassis plate. In order for one to work for me, the threaded portion of the jack must be about 3/4" long.

Does anyone know if such an animal exists?

Albert, I nixed the Cardas because it can only work in material up to material .4" thick :(. I'm getting desperate. Is there anyone that can machine a set for me? It's a relatively simple part. I think the hardest part to get right would be the part that clamps the pin.
Ketchup, I was using Magnan ICs w/ my Bryston, and their barrels were just toooo big. I solved the problem with Monster right angle adaptors, but it was a less than desireable situation. If Albert suggests Cardas, I'd definitely check it out. They'd be good quality. Maybe they'd even make you some custom for not too much. Also, check w/ Jim Aud at Purist, he does a lot of custom stuff.
If such an animal exists, Stuart at Vampire wire would know. Call Sound Connections and ask him.
Ketchup,

Check out the new Furutech FP-901G at VH Audio. Although no specific measurement is given (literature says "Mounting Insulation accommodates chassis panels of any thickness") it looks as if there is at least 13mm (1/2") for the panel. If you countersink a larger hole (say about 21mm (> 3/4")) in diameter (for clearance) on the interior of your panel about 7mm (> 1/4") deep, it should give you enough room to "flush mount" the Furutech. Look at the spec sheet and talk to Chris at VH Audio to see if this is feasible.

Hope this will will at least inspire even more thoughts if not provide you with a solution.
