For a '68, are C20 and C30 rear axle drop outs the same?

Need to change gears from a 5.14 to a 4.10. Thought I would look for a complete dropout assy. from a C20 to put in 10,000 GVW Std. axle dually C30.
Will this work?

Thanks,

Steve weim55 Colorado

I can't honestly tell you, but I can tell you that the C20 would be an HO52 and the C30 would be an HO72. I would think they would be different....

Leon, I *think* the internals are the same.... differences are in brakes and axle bearings. That should be confirmed though.
