Sho cluster in a 96 lx

I was searching car domain and i saw a non sho taurus with the 150 mph sho cluster in it. I searched ebay and was informed that it will drop right in and function flawlessly if I have the stock 120 mph speedo which I do. I want to know if anybody else has heard of this, seen this, done this, or has any ideas. Also, If i buy an sho cluster, how hard is it to intall those reverse glow gauges i see on ebay for them. This could be sweet if it works. Thanks in advace.

yes, it is plug and play

Those glow gauges on ebay are a real shoddy piece, I bought them and don't recommend them.
