This is the plan for my 1200 Ute. 1200 coupe dash (round gauge style). 3x 3 3/8 inch autometer gauges. Tacho, Speedo and a Quad gauge. The quad covers Oil Press. / Water Temp. / Volt / Fuel Level. You will need to put their sender into the tank and adjust to suit but well worth the work imo. Beauty of autometer is they will custom make. They don't have all 3 in 3 3/8 all in the same series but if you go here (Autometer custom shop), they'll make it any style, colour and font you want.

The only thing i don't like is you can't get the quad with the temp gauge in celsius.

This doesn't include a boost gauge though as i has no boost :( lol
