Default 1986 AC Compressor Bolt & Brace

Looking at the rear of an 86 L98 compressor, is there a brace at 12:00? Or is there only the one brace at 6:00 that bolts to the exhaust manifold? Just making sure I'm not missing a brace.

Also, is there any way to completely remove the bolt at 6:00 without disconnecting the AC lines? Thanks.

Nothing else at the back side. Leave the bracket at 6:00 in place, but loose. It does not have to come out. Then remove the end at the exhaust.

Thanks, Jack. I need to replace the bottom bolt. Can that be done without removing the AC lines? There are some stripped threads in the front side of the bracket and I think on the bolt threads, too.

You can get a lot of wiggle out of the lines. I am trying to remember the brackets but cant. Sold my C4 in August so I have no reference.

The bottom bolt head hits the metal AC line when pulling the bolt back. I'm also looking for a complete compressor bracket for an 85-87 if anyone is selling a used one. Thanks.
