Fan shroud questions for 79 k5 blazer

[Ramba_ral]

Hello all
Im havign a issue finding a replacment fan shroud cor my 79 blazer its a 4x4 350 with ac. I can find every kind of fan shroud exept one that matches my setup. My question is 2 fold . whats the difference between a ac and non ac fan shroud and would it be bad to use a non ac fan shroud in a ac truck?

The shroud depends on how thick the radiator is. It can also make a difference with the height of the radiator.
I don't know if the shroud part description has those details.
Quite often having A/C meant that a 4 row radiator, but I don't know if that is ALWAYS true.
So it's possible for a non air shroud to be too short and not work with the radiator and mounting. And the distance from the radiator to the engine fan varies based on the number of tube rows in the radiator. The thickness of the radiator changes this.
