Short Shaft Fan Clutch

Where did you get the new fan? Have a part number ?

The Chevy part number is 14034027. I don't believe they are being repopped. Here's the NOS one I picked up off ebay for $45:

New GM OEM Radiator Fan Blade, 84 - 85 Camaro 5.0, 14034027 | eBay

I bought it thinking it was 17.5" in diameter. When it arrived, I measured it at 18-1/8". I had to widen a couple holes on my radiator mounts and shroud mounts to move them over enough to clear the shroud, but it does, barely.
