i'm looking at changing the stock fan in my '99 Silverado Z71 4.3L V8 with a
perma-cool cool-pack unit. i've found a great deal on a unit but it is for a
17x28.5" (part#: 19517) radiator core but i have a 19x34" (part#: 19516)
core. i've seen several sites that say the 17x28.5" unit will work and i
know the mounting holes are the same but i wanted to get some of your
opinions and/or see if any of you have made this kind of application work.
below is a link to perma-cool's website should you need a better
