Hey guys, I'm setting a friends 68 goat with AC right. currently he's got an 11 bolt cover/pump on there with the 128 pulley from the 70 setup on the water pump. when I put the 68 timing cover on there it's going to shorten up the water pump neck when it goes to the shorter 8 bolt pump. Everything is stock on the car with factory rad and shroud and that fan with the clutch is just about out of the hole now with the current setup. Once I put that 68 pump on there it's going to come out of the shroud all the way. I've got a 75 parts book saying that they used the same fan clutch from 64 out. doesn't seem right to me, I'd expect that fan clutch for a 68 to have a longer neck to push the fan in deeper. no way they used a spacer between the clutch and the wp.

I could swear I came across info somewhere out there on the web that there were different fan clutches for various years but of course I can't find anything on it now. Not sure if GM just consolidated it all into one number for ease of inventory or what. by 75. anyone have any insight on this?

anyone with a correct 68 (still running 8 bolt cover) with a fan clutch and stock shroud that can show a pic or take a measurement of where the fan's sitting for me?

Thanks,
Dennis
