Yup. The one with that clutch I got was the same. No big deal. File the bushing down. On the fan is it simply excess paint or powder coating on the edges? File that down as well. Any replacements would likely be no different i bet. And put a section of cardboard (like from a 12-pack or 24-pack) against your radiator, and bolt it up.
It's just another piece of aftermarket BS that doesn't work. In particular, the fan that doesn't fit the clutch. Can someone tell me what OEM clutch fits a 70 340 with 18 in. 7 blade fan in a 70 Barracuda.
