ok as im sure 99% of u know i have a 99 rcsb, the guy doing my engine swap says i need an oil cooler, but i dont have an oil temperature gauge. i figure if im gonna get a cooler, might as well have the gauge too, so does anyone have any idea if i can put like a silverado ss cluster in my truck being that my truck is a 99??? also if i go aftermarket can i just mount one on my dash by the passenger side air bag on/off switch??? brandon has his boost gauge here, so im sure thats possible!
