Search for an "Original" 240Z Resonator

[CW240Z72]

I am knee deep in the middle of restoring my '71 Z and on a hunt for the center resonator for the stock exhaust system. As of now I have the JDM Car Parts downpipe and repop of the original muffler, but its the bits in between that I cannot find. 

Has anyone came across a close alternative to the Nichira resonator? I have looked across the internet for one that's close but they are either too wide or too long to fit in the trans tunnel. I have one with me that measures roughly 6" wide and 12" long on the canister. It's not useable unfortunately.  

The best packaging resonator I have found available is one that is round in canister shape, opposed to the oval shaped Nichira one. 

Here's what I'm after (pics taken from other CZC members): 

And here's the best packaging resonator I could find: 

Here's the car I am after the resonator for. Thanks

Hi, I see you have already my pic of the mid part of the exhaust!  Your resto deserves a part like the one on my old garden table haha.. It went to @Zup maybe he knows a copy or can give measurements of it..

I just had one of those for many years on the attic and never used it. At the moment i have a aftermarket 260z exhaust under my 240z, it has a bigger diameter pipe, and it's a little bit louder.

I like your work very much, well done!  Hope you find something you can use for this perfect resto!

Diameter original (exit side to end muffler.)

 

The part Nr: 200050-N3000

Thanks! I figured finding a good original one would be next to impossible. Hopefully someone has already been down this path and has a close aftermarket substitute they could recommend.

Check with Mike McGinnis at Banzai, he might have one in his NOS stash that he willing to part with.

Good idea, thanks Jim!

I have searched far and wide across the internet for a resonator of the right size. Reached out to Banzai in hopes that Mike has something hidden away. I did come across one I think would be a good fit, from our friends down under 

Measures 5" x 3" in cross section, 12" long, sized for 1.75" pipe. If I can get them to ship it to the US I may be in luck!

I don't know how real this site might be, I've never seen them before.  But the part number came up.  Not sure if "A tube center" is the same thing.

That's interesting, doesn't hurt to reach out and see if they have one in stock. Thanks for digging that up.

A tube center sounds like a piece of tube for cars that don't have the pre-muffler?  Maybe the part nr can be found in a parts catalog.. looks like a 240z part number.

If you can't find the original I know this one fits since it's on my car and tucks up nicely in the drive line channel.

That’s a good alternative. Did not come across that one yet.

So I took a chance and bought the Australian based muffler. Turns out it’s a pretty close alternative to the “factory” style one. 
 

Side by side with the exhaust that came off this Z. I don’t think this was a true original piece, looks like someone spliced it in some time ago. Either way it’ll have the look I’m going for.
