Yes, it's a straightforward swap. The new glass comes with integral trim, and is usually available, installed, for less than $200. And often MUCH less than $200. I paid $135 last time. I prefer the later model (91-93) glass.

If you take the car to a glass shop, they might not be familiar with the swap. You can just tell them to treat it like a 1993 240.
