mounting options include:
the drivers A-Pillar
over the rear view mirror
or Under the dash.
your guage choices are staggering & confusing...
dipricol, isspro, & autometer are three that come to immediate
mind (and both have different faces & styles...autometer
must make 2 dozen different styles or more).
you can diy the guages OR buy 'em completely mounted
in the mount, already wired and ready to install/hook up.
a few of the good "online retailers" (that ive personally used
& in NO particular order) are:
DPPI
DieselSite
ITP Diesel
Diesel Innovations
when you install your EGT do yourself the favor and install it in the exhaust
manifold...its mentally tough to drill holes in a brand new truck
but the egt measurement is more accurate in the manifold and is
the most accurate reference point.
other sources (but not DIESEL forum sponsors...which support
and pay for this FREE forum/site btw)...
Summit Racing
Jegs
also consider adding a coolant filter (it will extend the life of your water pump
and collect all the sand left behind from the casting...itll clear up your
overflow bottle in a matter of a day, making it easier to see the coolant level)
order yourself a couple of extra filters...the 1st two plug up from sand/castings
pretty quickly.
