Digital Speedo?

[Factory Guy]

After reading Ls1Nova71 Digital Speedo swap he inspired me to build my own tach for my Squarebody and it turned out Great!

Now I want to do the same thing for a Digital Speedo and I tried using the S-10 Speedo, like he used in his write up

In preparing to do the speedo conversion, today(bottom photo), I noticed that I would have to cut out a big hole in the back of my Squarebody instrument cluster, which isn't a problem other than it would require me to cut out the body plug that powers the instrument cluster, which I DONOT want to do.

Thus I am looking for some input. Does anybody know of a GM (circa-1990-2000) Digital speedo that is quit a bit smaller than the S-10 speedo I was going to use?

I realize I COULD get a 88-91 Blazer/Suburban instrument cluster, but since those ONLY go to 85mph, that will not be an option.
