When you say...

205 shifter bolt sizes are they all 9/16 or they change from years

9/16" you mean the head of the bolt? If so diameter of the head is not in reference to the diameter of the bolt, a 9-16" head size is usually a 3/8" diameter bolt, a 9/16" diameter bolt usually has head size of 13/16", there's a diagram in chitons repair manuals ie:

I think the thread size was the same for all years, but there were different bolts used. I think the later style had a smaller shoulder because the shifter had a bushing in it. There may have been one or two other variances also.
