93 gauge install

[93yukon]

Is there anyone who can point me in the right direction for a gauge install on my 93 tbi? I'd like to know what's needed for mechanical gauges (water temp and oil pressure) any help is greatly appreciated as I'd like to do this in the next couple days. (I tried a search and it came up with so much I couldn't go through it all) I'd like to retain stock gauges as well as have a aftermarket trio under the dash or some where similar.


This is what I'm wanting to get
