Valiant -64 7.25 rear spider gears do not fit

I checked posts to my threads and didn't find any comments where this was mentioned. So I think it was somebody else.
I did search but didn't find any relevant content, maybe my keywords were not good.

If those do not fit, which rearend they are meant to? And is there right ones available and how to double check that they will fit?
I thought that 7.25, 9-bolt would all be same but I propably was wrong again. :(
It may have been. My memory isn't what it used to be. I'm sorry you found out the hard way. That stuff is for the Dakota 7.25.
