No problem. God bless and sorry for your loss. No worries about the cost I can return them. I never got 2nd gear so I can't check that but I do have the thrust washer that goes between 1st and the rear main bearing. That thrust washer bumps up against the shoulder on the mainshaft. So I measured movement of 1st gear with the synchronizer assembly all the way up against the snap ring-from the synchronizer assembly to the end of the shoulder ,which is where the thrust washer goes. I do have the factory service manual pdf. In the picture below the snap ring the red arrow is pointing to -actually goes in front the 1st/2nd synchronizer assembly between that and 2nd gear , even though in the picture it's exploded behind the 1st/2nd synchronizer assembly , right ? Because if I'm not mistaken ,sometimes the order of the parts in exploded diagrams is not how the parts are when they are assembled.
In the picture there are only 2 snaprings shown in that area.
The 3rd photo shows rear side of the mainshaft behind the 1st/2nd synch. assemb.
