a way to make the sunburst RWD?

I've been playing around trying to make the Sunburst RWD, And the car does not move when i put in the RWD Transfer Case.

Any help? I think it's me being stupid on my part.

 

Put a rear diff?

 

Did you remove the front differential and install the rear one?

 

Break the front drive shaft

Boom

 

I don't see a rear diff on the sunburst, it's just race, open slip, and normal

i even removed it and there was still no rear diff
