p.s. after perusing a few vendor parts sites that sell pieces for our trucks... most of 'em want around 75-85 dollars for the same heater core.
O'Reilly had it for $34.xx(tax included).
Maybe the vendor ones are precise exact copies or something? I dunno, but thought I'd add that in here.
UPDATE 03/14/2012 : if any of you wander in here and need tips on replacing the blower motor with the same kind of setup...
go here.
