I did mine with red led's
got them at

one thing you might want to do is paint the inside of the bezel. you will find the old bulbs have burnt spots in the bezel. I painted mine a reflective silver but I think white would have done just as well.
don't change the gen lights.
Led's wont dim without a special dimmer and the bulbs also have to be capable of dimming. if you figure all that out then please post it.
The red led's I used do not need dimming. they are perfect for my liking.
I am using a civy cluster set up with gauges so it is not the stock cucv cluster and I have moved things around but that does not really change anything with the LED's I am still using the printed circuit board and the stock light bulb locations in the cluster.
you can search my post. I never got to complete my wiring diagrams so if you run across any that I posted, be ware of errors. you don't need the wiring info to just change bulbs.
good luck
