King Air gauge help

[leversole]

Asking if someone would like to help me? I would like to update a few of the King Air gauges to match the red/green arcs on the xPlane gauges? The limits on the prop speed and Turbine and Temp need adjusted... I tried to modify them but starting with a bitmap and adding vectors and converting back to a bitmap doesn't look very good! I use the king air engine gauges for my home built cockpit.

Thanks in advance!
