Does anyone know the difference between the rear quarter glass (RQG) on a 2dr Blazer vs a 4dr Blazer?

I would like to replace my RQG because the affixed window molding has the notorious pitting and fading. The other day I saw a 4 door blazer with the same body style (2000). It appeared to have the same RQG pushed back the length of the rear door.

Thanks in Avance

I forgot to mention, in case you don't already know. The reason for my question is that there is a drastic difference in the price of the glass.
The 2dr runs $300-$500
The 4dr is about $200. $170 from LMC.

 

The curvature of the 2-doors rear glass and the plastic molding is completely different than the 4-doors. The 2-doors have a bigger radius where as the 4-doors are more flat.

Also, the rear glass on the sides, with that plastic trim are normally affixed to the side paneling of the truck if I recall correctly.
