evo 5 door replacement Rs or Gsr

[alanevo456]

I need to replace an RS front pass door but these seem to be hard to find. Does anyone know if the doors that come with elec windows are any different weight wise internally. I am told the glass is different but need to know if there is any additional bracing internally to support elec windows.
The GSR doors seem to be more available but weight is an issue.

Surely the doors will be the same?
The GSR ones will just have a lot more gubbins inside them.

Wasn't electric windows an option on the RS's anyway?
