Dana yolk

Needing to restore my 1970 dana (410) rearend. I have an aftermarket ( direct connection) pinion yolk
I'm not sure what the original part # is in order to look for it. Any help will be greatly appreciated. Thanks in advance

Got an answer...#7290

Just my opinion:
That will get you the right fitment part but that is the yoke size classification, not the actual part number for your car. But, as long as you get the yoke that works, which you should with that info.
