Buying up some gauges and have some questions

So I have decided to buy up some gauges for my 1975 280Z SR20det project.

Prosport 52mm tinted glass gauges:

Air fuel

Boost

Fuel Press

Oil Pressure

Oil Temp

Water Temp

Volt

(maybe)Exhaust temp

AM I FORGETTING ANY?

5" Cobalt Autometer Speedo and Tach

One thing I am considering doing is just putting 3 of the gauges in the stock location, then affix the rest to the top of the dash like in the first picture. The dash is in pretty bad condition, and I am going to be doing a custom fiberglass dash project which will be wrapped professionally in suede. At that point I will conceal the gauges better, but for now I think im gonna go "drift" style.

It comes priced out to $868 before tax (gauges + 5" tachs) - is there a cheaper alternative? I mean, I gotta have all my gauges right? Cant be running lean or too much boost.
