'69 and earlier small block AC bracket

I think i might have one from a 67 Coronet 318 LA. Do you know if the main compressor pulley or clutch have to come off to get the bracket out?
Yes clutch and magnet have to come off. But its super easy, run center bolt of clutch out, then you run a course thread 5/8 bolt into existing threads in center of clutch hub. That 5/8 bolt pushes clutch off of shaft as you tighten it. So basically the 5/8 threads which are visible after that bolt in center is removed is like a built in clutch puller. Super easy. Then clutch magnet is three small bolts. Its about the easiest compressor clutch on planet earth to remove.

The bolt needed is 5/8 - 11 around 2 1/2 inch. At my local hardware store thats the run of the mill regular 5/8 course thread bolt nothing special.
