Re: 1979 Chevrolet C70 Conversion to OEM Air Conditioning

You're welcome, we did our best to locate things when I worked at the parts store and that stuck with me. I look up my own parts before I go to the store to avoid unnecessary headaches haha. Seems like that fan would work, the 2" difference in diameter shouldn't hinder the cooling any I would think. The depth that the fan goes into the shroud is important for sure. The height of the 2797 clutch is about 3 5/8" roughly. The bolt spacing for mounting the clutch to the pulley/pump is 2.5".
