What years for electronic speedometer?

I'm planning on a 4.8 swap before too long, so my mechanical speedometer won't work.

What year electronic speedometers work? Do I need to do anything strange to remove the gauge cluster, or is it all simple?

Thanks for any help.

90 and 91. Gauge cluster is also different from the 89 and earlier, which allowed the electronic speedo to fit into the cluster spot.

The 89-91 has a different grill and headlights then the older ones which should help to spot one in the junkyard.Or become a supporting member and put a add in the want to buy and let someone else do the leg work for you.
