I'll have to check again, but I didn't think the R32 GTR had special placement...
The three gauges go on top of the dash iirc.
The funny thing is, the R32 GTR came with a a bunch of gauges from the factory (Fuel, Eng Temp, Boost, Oil Pressure, Oil Temp, & Voltage... You can see them all while installing the aftermarket gauges), so in my eyes, the R32 doesn't really need more gauges
My SSR7 R32 has an aftermarket speedo that goes to 420km/h, but that's the only gauge I have in all my R32s.
Edit: also, the Blitz ER34 has the gauges in the console just like the R34 GTR. I haven't checked, but my guess is the Mines BNR34 is the same.
