I believe the number is 1116104, listed in the '59 Delco Catalog as '55-56 Chevy V8Bill Clupper #618 -
Re: 1955 vacuum advance --Joe Lucia or ??
I would have thought that the vacuum advance from a 1955-1956 v8 chevrolet would have been the same for a vacuum advance for a 1955 v8 corvette. I guess that is why the seller advertised it as corvette also. Any way , thanks bill for the response.Comment

Very often, the distributor vacuum controls used for Corvettes are different than those used on passenger cars with similar engines. However, in this case, the vacuum advance used for 1955 Corvettes was the same as that used for 1955-56 passenger cars. The vacuum controls used were GM #1116085 (early) and GM #1116104 (late).
It's also possible that some very early 1955 Corvette distributors used no vacuum control, at all, but used centrifugal advance only. I can't confirm that, though.In Appreciation of John HinckleyComment

Re: 1955 vacuum advance --Joe Lucia or ??
according to my judging guide the v8 uses 1116085 early and 1116098 late. No mention of 1116104. The lll6098 has a non operating vacuum control and is blank where the vacuum line usually attaches. I have been looking for the
1106098 for eleven years with no success. I do not know the precise use of the lll6104 and was hoping it would work but it has a hole for the vacuum line and therefor not correct..Comment

the one your seeing on E-Bay has a good pic.and it's In the right position and you cant see a number casted in to it, as the original would have, it's a replacement . This is what you should see if it's original, this is my 55 unit early!

I can find no record, at all, of the GM #1116098. If it ever existed, it was a PRODUCTION-only piece. So, you don't need to be looking for any NOS examples----the only thing that you might be able to find is a used piece.
By the way, the GM #1116085 and the GM #1116100 vacuum controls were discontinued in 1956 and replaced by the GM #1116104. However, the GM #1116104 was not a then-new part at that time. It had been around for, at least, a year. My records show that it was the vacuum control used in PRODUCTION for late 1955 Corvette distributors. The 1116100 was not used for Corvette distributors; it was used for passenger cars only.
Obviously, the above information comes out of historic parts information that I have. It is definitely not based upon any empirical information since I have no experience with these cars, at all.In Appreciation of John HinckleyComment

The advance
"can" is the 1116098, not just an original, the original. The engine block has been replaced, but since it was in the family the whole time, all the accessories were saved and installed on the replacement. The only detail item missing, and had been missing since I was a small child, was the big Mallory capacitor on the distributor, which is part of the RFI shielding. Found that one NOS fairly inexpensively. "Corvette" suppliers offered them to me for around $200, but I got lucky and paid about 1/10 of that. I am very glad to have the braided covers for the distributor and coil lead wires, as far as I know these are not reproduced. It might be possible to find braid that small to make them. The ignition wires are available, along with the braided covers, but I still have 8 of the original 9 covers. Some fool in a service station threw one away in like 1963, so I had to get some braid to re-cover one wire. Sadly, the 55 repro wires are not available without the shields.Comment

Yeah, red, and the wires
I mentioned connceting the coil and distibutor can be seen here.
I got weird conflicting advice from local restoration shops concerning 55 (and 56) engine color, but eventually I heard from you, Ken Kayser, and Noland Adams, and I was all straightened out after that :o)
