flathead transmission questions/advice

[benbuilder]

I picked up two toploader transmissions from my uncle this past weekend. I am looking for some advice and reassurances that i am correct in my thinking. I painter them two different colors so i dont mix up the parts.

The Blue one I believe is a 1932 based on the ser number, but the casing tells me it is a 1933-1935. pictures to follow.
48-7006-J
18-42659-unless i cant see another number???
It had the complete shifter slanted tower 40-7222 in it, but i think this is a 1936 shifter

The gold one i believe is a 1936
48-7006-H
18-2240299
Shift tower only, no stick, one detent, and i can only read 222
The gold one has slanted gears on the main shaft, so i think this is the better one to build. The large gear has some chips in it, so i need to replace it.

Do you agree:
I should rebuild the gold one?
the gold one is a 1936?
I can use the blue shifter and forks on the gold assembly?
What else do i replace if all looks good except this one gear?

Thanks
