Different Radiator supports for different engines?
 

Does anyone know off the top of their head if there is a difference between a 5.0 Radiator support and the 5.8 liter? It's one of the last pieces I need, and found one for a 5.8 already out of the truck. thanks!

Shouldn't be any difference there. The 6 cyl non-A/C rad support was different, had a smaller opening, but can be cut out to accept the larger radiator.
There is a difference between early and late models though. Early models used a brass/copper radiator, and had a top/bottom clamp mount, while the later ones used a plastic/aluminum radiator and had ears sticking off the sides to mount it.

Thanks RW, that was the answer I was really reall hoping for. I found out that there was a change in '85, as my donor truck was an '85 but my 4 row radiator is made for an '82. Don't like zip ties holding it in

Just send me the 4 row radiator. I need one, but will have to get different tanks installed..... I need it in 6 cyl configuration.
