The left side final drive doesn't look too promising
Here are the pinion shafts and what comes out with them.
Arranged here we see one bearing retainer was missing
With that and new seals these will be fine.
I got a replacement bull gear from a WC thinking they were the same.
Oh no we couldn't have that! The WC gear is 3/8 of an inch wider.
The WC bull gear is the same width as the pinion
The narrower RC gear runs down the middle of the pinion
The inner bearing cup for the RC bull gear standing next to a WC cup
The inner bearing cone for the RC uses a spacer to hold it out a bit on the axle.
Shown here next to the equivalent from a WC
The pinion shaft and everything that comes out with it from the differential.
The ring gear looks good and shows the 5 33 ratio vs. the 7 32 ratio of the WC
