removing spider gears 7.25

I believe the split was going into the 74 model year and that's when they went to C clips
I agree none of this helps the princess.

But I checked rock auto and 7 1/4 up to 84 (diplomat) used a sealed bearing. 8 1/4 uses the roller bearing that rides on the axle shaft and needs the c clip.

And there is no call out for a 7 1/4 c clip till the end of the 7 1/4 in 84 or thereabouts
