Can you post a picture of your cowl tag please?
Trying to post can you text me
Doug sent me a picture of his cowl tag, the decode is shown below.
STYLE 64-4367 KC 2172 BODY
TRIM 141 F11
E 2P 4F 5W
04D = build date = April (04) 1964, fourth week (D)
4367 = style number
4 = Buick
3 = series 4300/Skylark
67 = 2-door convertible
KC = built at Kansas City, MO
2172 = 2172nd 4367 built at Kansas City
Trim 141 = Blue Vinyl, available on style 4367
Paint code F = solid Marlin Blue Metallic
1 = white convertible top
(not sure why there are two 1's stamped)
E = Tinted glass (all windows)
P = Back-up Lights
F = Remote controlled outside driver's mirror
W = Seat Belts With Retractor
Group 2 option code L is 4-speed manual. Your car doesn't specify a code for the transmission type, either manual or automatic, so you can't tell what it came with from the trim tag. There were several option code schemes (at least four) in use in 1964 and different plants put different things on the cowl tag. I've even seen some tags that had "4-spd manual" stamped on them. So unfortunately I don't think the cowl tag is much help for you.

There are some other items to look at which should help pin down an original 4-speed car. There were only 3 transmission choices on Skylarks that year: ST-300 Auto column shift, 3-speed manual column shift and 4-speed manual floor shift.
The steering column would have had a backup light switch mounted on it if an auto or 3-speed were installed. There should be no evidence on the column where a backup switch or neutral safety switch had been installed. Likewise there should be no slot in the shifter bowl for a gear shift lever. Shouldn't be any shift arms present at the bottom of the column under the hood. There should be no Park RNDL indicator plate in the instrument cluster.
The backup light switch wiring under the hood was run in a unique left side engine wiring harness used only on the 4-speed cars. See attached page from the shop manual for wire routing. Non- 4-speed cars had only 6-wires coming out of the left harness bulkhead connector under the hood. 4-speed cars had 8 wires.
A couple of other items to look at, if original, are less definitive. The carb will have a different part number depending on whether transmission was Auto or manual. The standard rear axle ratio for V8 automatics was 2.78. 3-speed V8s used 3.08. 4-speeds used 3.23.
