The wanting gauges and wiring harness is a "complete dash with accessories" ... The gauges for fuel, water, amps are the same as alpine s3/IV. The oil gauge is the same but with different rear fitting which you can get an adaptor.
Tach and speedo you could get the reworked alpine ones from thevguy making new faces , might be easier than getting original tiger gauges and they will be fresh rebuilds.
As for wiring, if going from race to street probably safer and easier to get a whole new harness either to original spec or one of Paul's upgraded modern setups.
Otherwise I think reword the ad to ask for complete tiger gauge set
