Perk, put your rig info in your signature, at least year and model
*Edit or does having the PWR light maen that you have the later highly refined transmission and therefore the later dash? did those changes happen at the same time?
I did it in conjunction with other dash activities that took all day, I would guess you could probably do the bulbs in 2 hours if you hustled ( I never do ) the cluster has to come out and then you have to remove a separate box in the cluster, you will need the bulbs from CDan, they are special doubt you will find them in a parts store,
Take a look at the FSM but here are a basic description for the later dash from beer soaked memory: take off the kick panel, then the column shroud (top and bottom) tilt the wheel all the way down, remove the middle dash piece that has the mirror controls, locker rotary switch on the left and goes over the wheel to the ignition cylinder on the right, then the black piece around the cluster that has the two vents, this black piece it captured by the dash pad on the far right side, dont try to force it before finding the catch or you will break the vent (

, superglue fixed it) then the cluster itself, about half way out you need to unhook the 4 (or was it 5?) electrical connectors on the back of the cluster, be very careful with the exposed printed circuit plastic sheet on the back of the cluster touch it as little as possible
At first it looks like it should come out to the left (basically out the door) but I could not get it out that way, after some rubix cube action I got it out to the right.
After you get the cluster out there is a box in the middle that has several tabs, it was stubborn at first but after I got all the tabs clear and
gently pried in the right spot it came right out, on the now exposed side of the box are the bulb bases, give them a 1/4 turn and they come out.
when you go back in work the harnees in deeper over the duct running behind the cluster if you do not it will get cought and the cluster will not sit flush
