Alan,
I must modify my statement regarding yoke 42-5035/5036.
I was incorrect stating that one was a casting number.
Having checked the parts book and finding both listed, 5035 for A group and 5036 for Road Rocket, they are the same casting but the difference being the Road Rocket part is drilled for the instrument bracket hence a different part number.
As far as I know, Goldstars always used 42-5010.
I suppose the answer in your case depends whether your frame ever had or has the lock receptacle on the headstock.
