Here's another auxiliary cooler install. I followed PhilD's writeup with a couple of subtle changes.
I got this Hayden Imperial Maxi-Kool XL cooler from Advance Auto along with the hose barb kit, extra clamps and another three feet of hose.
Notice this is the 243012 it's pretty big at 11 x 11 3/8 x 3/4 thick (the only one they had in stock).
I drilled and tapped two holes in the cross bar for L-brackets.
Set it in place in the center with just enough room to clear the hood lock. I shot everything with a light coat of flat black grill paint to make it disappear. The Hayden cooler comes in a gloss black finish.:nono:
There is an existing plastic tab on both sides that lined up perfectly. I bent the upper brackets in the vice from some larger L-brackets I had laying around.
