syncro slider

[Dmichels]

Need a little help ID 2 of the 3 versions of the syncro sliders. The first type is easy it has a narrow grove on the inside. The 2 later types have a have a wider grove on the inside. I believe one is deeper then the other on the 2 styles. Can anyone shed some light on this? I am going threw my trans with a fine tooth comb and sorting out the problems
Thanks Dave

I believe the wider groove is late '70 and later.
