I have searched to find info about the speedo drive gears in the 4 speed SM 420, and have learned that there may have been several different matched sets available. I have found gears for sale, but want to confirm what I have in there,

I found this picture from Denny's post

So, does the yoke just pull out if I remove the big bolt on the end? Or will I need to remove that end cover plate too, to confirm what is in there. ?
