WE code rally wheel

I have 3 buick rally rims. The code Is WE on the inside lip. Can anyone tell me tell specs on the wheel and will they work with the one wj rim I have.

 

They physically interchange. The WE wheels are lighter because the center is flatter.

 

Thanks for the reply. What are you referring to when you say the center is flater? So backspacing, bead and offset are all the same? Will they be noticeable if I use the 3 we's with the 1, wj?

 

Look at the stamping of the center. The depth of the lugnut pockets is different. If you can't see it looking at them side by side, no one else will either. Use them.
