Diffrence 7 1/4 bolt in and c-clip?

Hello from Sweden.

I have a plymouth valiant 1965 with a 7 1/4 axle bolt in/retainer driveshafts 9bolt cover.

After a breakdown in the diff i have been trying to fix the spider-gears and has been looking for parts

I was told that c-clip gears should fit but it dident.

Anybody knows if it is differences in the carriers from the c-clip and bolt in/retainer axle.

Casting number in the carrier is 2070536
