Radiator/Shroud Mount Questions

[LuvNLife]

OK; just bought myself an '85 C10 short bed; it's a bit rough, but sure worth bringing it back. Now, among the things the previous owner did was to pull the radiator, and install an aluminum one with dual electric fans. Now, some folks will think I'm crazy, but I want to go back to a regular fan, clutch, radiator and shroud. The only piece I have is the shroud itself; all the rest had been tossed. I've figured out some of this, but have two questions: 1) on an '85, what actually holds the radiator in place - brackets or a top plate; and, 2) what does the shroud actually attach to, top and bottom?

Thanks for any help...
