[Spridgets] An aluminum question for the engineering/machinist type out there

[John Innis]

You will have no issues using 1/4" aluminum plate.  I find for applications
like this the thicker stock works fine.  This application will not be under
load and 1/4" aluminum is really quite strong.  One upgrade you might want
to make while you are at it, this is a great place to add some extra PCV.
I have seen several folks add a port to the fuel pump block off plate on
the 1500 and use it as an oil return for an upgraded PCV system.  NIcer
than having to periodically empty a catch can.  Just make sure you don't
use any of that steel-wool looking stuff in the separator.  That stuff
comes apart and eats the oil pump.
