Not sure who you spoke to, but I'd call them back, and tell them "direct fit" means "direct fit"
They bolt in, and they have the side mount brackets.

SUM-380456 (double check that number on the Summit site to make sure)

The only thing you'll have to do is modify how the fan shroud mounts. I drilled a hole in the bottom of the factory shroud, used a sheet metal screw, and used a piece of metal (strap) and ran it to an existing hole in the core support. Fits nice an snug. End result is that the shroud is held against the radiator, with a bolt on the bottom, and the factory bolt on top.
