I had mine rebuilt by these guys:

They also put in green LEDs and installed a trans temp gauge.
My total cost was $280 for the repair. They did it pretty quickly: I shipped it to them on a Tuesday afternoon, they had it by Thursday, rebuilt it on Friday and shipped it back to me. I had it on Monday evening.
Interesting to note that your 2500 does not look like it has the Drivers Information Center (DIC?) I wonder if that's because it was still an option in 2001 or maybe because yours is a 2500 and not a 1500?
Either way, there are fixes out there. I had the same issue: My PRND321 display was unreadable except at night. Now it's nice and bright and I have green LEDs in there too.
