Re: early 63 fi S tube.
The very early 63 s-tube is heavier gauge metal. I have only seen two in my life. All you have to do is knock on them.
The overlap on the first s-tube might not be the same configuration at a typical s-tube. I seem to remember that looking at one at the Hershey National convention. The overlap looked more like Podells first repro.
I cannot answer your question in detail. One would have to provide you with a lot of pics.
Forget to say the originals and Podell's second repro have wrinkles or crinkles on the bend. That's all I know. John -

Re: early 63 fi S tube.
And Robert you thought this would be an easy question, it's a corvette and 63's are even worst. So how about a little more information such as an approximate build date (general VIN will get us there) And any specific questions.Comment

Re: early 63 fi S tube.
There is a NOS one on line for major bucks. Maybe you gurus can check it out.Comment

Re: early 63 fi S tube.
this has nothing to do with any particular vin #, just wondering how to tell a service replacement type vs. a factory type. my car is mid nov.Comment

Re: early 63 fi S tube.
I don't think there was any difference between GM supplied service elbows and the original, but there have been a couple of repro versions that differ significantly from the original. I have an original in storage (not for sale), I can post some pics tomorrow...
You can get a nice ABS plastic repro for 'only' $295 on ebay right now...wish I could find an ABS repro canister, (if there is such a thing)Mike

Re: early 63 fi S tube.
If I was looking at it to buy, I'd notice that it is missing 'ITI' logo on the tightening band, has additional spot welds on the top seem, wrinkles are different than other S tubes, the nut on the band is welded on upside down and the band is on upside down. Maybe there was a second vendor for these service replacements? OR, maybe it is one of the early 'thick' ones for 63? JD, where are you?

Re: early 63 fi S tube.
Hey JD, is the NOS one on Ebay like the 'thick ones'? Or is it a total unknown? Thanks, inquiring minds need to know! Thanks,

Re: early 63 fi S tube.
Dan, I didnt' realize the post was going on. How is Poor old Jd supposed to know if the s-tube is thick or thin by a photo??? Remember the old saying that a photo is worth a 1000 words. LOL
Regarding the upside down band Dan etal (and others). My 63 FI car has a band that's upside down also. THose are not typical of mass production but it was done. You can see how a fellow could easily do this as you can't tell the top from the bottom sometimes.
Yes the seam on the one in the photo is a tad different than ones we are used to seeing but that doesn't mean it's not original. The seller did say he has had it for an eon and I would like to believe he's telling us the truth.
One may never find an early S- tube Robert. You originally asked for info on an early s-tube.
I have only seen two. Maybe Jorjorian will jump in and say if he has seen many early '63 s-tubes. The gauge of the metal is much thicker.
That's about all I know about S-tubes. Except for one thing. You will see a 63-65 Fi air cleaner advertised and go to find out it's missing the S-tube. That's not right. An FI air cleaner has three major pieces. S-tube, cannister and 90 degree elbow.
You didn't ask and most of you FI owners know this but if you need a new element for your midyear FI air cleaner go to NAPA and ask for a '6418. Late 90's Ford product. Then put your screen on the shelf as you don't need it any more. JohnComment

Re: early 63 fi S tube.
JD, reason I asked if it could be an early S tube is the top seam doesn't over lap, it's just tack welded on top of other side without the raised lip on common S tubes. Looks like it was a 'training day' S tube at 'ITI'? Maybe it's the original proto type and worth millions?

Re: early 63 fi S tube.
Can't spend too much time on an Ebay ad Dan. The photos aren't that great. That's why it's better to answer questions here on a part if someone can post pics of the part they have or has the item in hand. Later as buried with work.Comment
