I don't know about the gauges because I'm using Autometer gauges for mine. I honestly don't know how all the stock gauge routing goes, but I bet it could be made to work, just need a tach signal for the computer if you run a carb setup. With the FAST I'm running a dual sync dist. and it makes everything easier in terms of engine wiring cause it's a standalone.

 

Here's a pic of a 10.2 deck 572 in a 4th gen. it's pretty tight, but very doable. headers are custom by MadMan.

 

the shock towers are way to close together and too far back in the engine bay
