Question: Were 66 Shelby 4sp. trans. always stamped???

[capecodmustang.com]

I've had about 30-40 66 GT 350's with a 4 speed...

I've never found a VIN on the transmission....

The federal law requiring automatic transmissions to be VIN stamped did not take effect until January 1, 1968. In general all FOMOCO products are VIN stamped on the transmission from the beginning of 1968 model year. None were stamped prior to 1968 model year. Only 4 speed transmissions and high performance engine assemblies were required prior to January 1, 1968.

Pretty sure we discussed this in the past on crashed forum 1.0. I'm not aware of evidence that any of the 65-66 GT350 T-10M versions (aluminum/aluminum, aluminum/cast iron, cast iron/cast iron) were VIN stamped.

And the T10M1's did not come with a tag, but will have an assembly date that should precede the cars San Jose assembly date.  The HiPo C4's did come with a tag and date code, also preceding the San Jose assembly date.

Royce, 67 427 Fairlane's were stamped with the Vin on the bottom embossment of the top loader.

Same with '67 GT500s must be the High Performance Engine assembly clause ? Only the transmission tho, not the engine.

It's just another case of Shelby doing what they did - Federal law notwithstanding.

So it seems that it is easy to come up with examples of original drivetrain 65/66 4 speed trains WITHOUT a vin stamp. Even one contradicts the supposed "everyone is supposed to " federal law.

Royce ,Shelby was not responsible 65-70 with determining which engine or trans got vin stamped. The Ford assemblyline where the car was initially built was responsible for whether a engine or trans got stamped or not.

Well Bob...
We do know how organized our federal government is.....

Quick question, how many had un-stamped blocks?

Since engine vin stamps were not a federal requirement till the 1968 FMVSS act did you find any born in k code drivelines with no vin?

[capecodmustang.com]

66 Shelby's should have a VIN on the block...
I've yet to see an original engine one without a VIN..

67 GT 350's?
That's another story....

I had a very original 66 K Code FB a couple years ago.
Documents....owner history...original paint....etc etc..
It had no VIN on the block..
However....
It was built in Metuchen and after some research I discovered many NJ cars did not have VIN's on their blocks.

  No vins on any '65 or 66 aluminum OR iron transmissions. THE reason was they were NOT standard issue T-10 transmissions and FORD did NOT have repair parts for them! A Ford dealer HAD to go to SAI for repair parts. Shelby specific parts did not enter Ford's parts system until AFTER SAI was assumed  by Ford after '67. No mystery here .

Just to add to the discussion....

This T-10 currently on ebay does have a VIN stamp so "assuming" it is factory, does show a location where a T-10 "could be" VIN stamped....https://www.ebay.com/itm/233790842662

The seller has the tranny totally misidentified as "1965 66 67 SHELBY BIG BLOCK T-10 4 SP TRANSMISSION Rebuilt High Nickel NOS Gears".  Interesting that the VIN decodes being for a 1965 Mercury Comet Cyclone 2-door, A-code 289, built at Los Angeles.  Don't know why that car would have a VIN stamped tranny to begin with?  Probably, as Randy just pointed out, this IS a standard T-10?  Were all standard T-10's stamped?

Well Stephen and his +1 is let off the hook given a least one has a stamp regardless of if a Shelby or not.

 Dave and Bob,
      "Regular production" four speeds ( high potential theft) , NOT three speeds WERE stamped . I currently have a K code Fairlane T-10 and several Toploaders ( pre '68) that are stamped. '67 SAI products ARE also stamped because they are "RPO" transmissions.

The 68 requirement was different in that it covered all engines and transmissions - before that it was limited to high performance only (engines and transmissions) apparently not well monitored and as always some (like NJ examples and apparently Shelbys for some unknown reason)  slipped through

Think I posted this in Forum 1.0
