Welcome to Allpar. What is the numbers on the case? Were you given any Mopar part numbers for what you need?

The 170 cu.in. is the light-duty transmission. The 2nd gear synchro kit is Mopar # 2464838. You can Google that for possible sources. I provided a link that I found by Googling: 'Mopar 2464838'.

I have no aftermarket look-up or cross-reference. Aftermarket part numbers are fairly meaningless to me. Sometimes looking up a Mopar number on Google will show you alternative part numbers.

The Mopar parts catalog only lets me determine the correct 2nd gear by tooth count. Is the trans together or apart?

So the 2nd gear has already been replaced and the original 2nd gear is no longer with the transmission?
Is there any part number on the gear or on the shop repair order? Does the shop still have their parts order receipt with the gear part number on it?
Is the problem with putting it back together that the gear doesn't fit on the mainshaft or shift fork?

The brass rings are the synchronizer rings. Is the 2nd gear itself OK and you just need the 2nd gear synchronizer assembly?

I am limited with non-Mopar part numbers. The best I can tell from the link is that BK299WS fits both a NP903 and A903 transmission. Otherwise there would be 2 different part numbers given AFAIK. Maybe the aftermarket listing is wrong? I would much more trust the factory parts catalog for being correct.

I was looking them up in the 1964 Chrysler passenger parts catalog here:
1964 Mopar Parts Book

On p. 21-12, see Synchronizer Unit (21-14-1). The standard duty one for Valiant and Dart is part # 2464838. The Heavy-duty transmission uses part # 2464835. So they are different. Those are the 2 synchronizer links that I sent you in post # 4.

On p. 21-9, they list a (standard duty) transmission assembly (21-02-1) for the 170 cu in. Underneath that they list a separate transmission assembly part number for the 225 engine, so there must be differences. They wouldn't use a different part number if they didn't have to.

The standard duty and heavy duty 6-cylinder; 3-speeds may be interchangeable as a complete transmission assembly, although with different, non-interchangeable components inside.
The standard duty 3-speed for Valiant V-100 (170 cu in?) is shown on p. 21-1 and the heavy duty 3-speed for V-200 (225 cu in?) is shown on p. 21-3.
The top cover and gasket shape (21-29-3 and 21-29-25) of the transmissions look different which may help identify which one you have. The top plate of the standard-duty looks almost rectangular while the top plate of the heavy-duty tapers towards the rear.
I'm sure that the 1964 parts catalog covers both North American and Export Chrysler Corporation vehicles. There is no mention about a transmission being different for U.S. or Canada.
