Title: WTB: '68 big block fixed a/c idler pulley
Post by: CharlesTurner on January 06, 2024, 02:33:33 AM: Looking for a good used fixed a/c idler pulley assembly for a '68 390/428. This is the one that mounts below the compressor.

Original Ford p/n C8AZ-8678-B

Thanks

*Bought one, thanks

Should be a 3 hole steel. I think the 2 hole cast would be for a small block, at least that's what is on a '68 GT350 that I'm working on also.

68/69 are supposed to be the same

2 holes cast for a 67 early 68 Big block also and they are easily confused but they are a different shape and will not interchange.

I had contacted Bill already, he didn't have any. Thanks
