Hi,
I took a few photos.
The right side of the 465, the brake, and the cable that goes into the parking brake.
Pretty sure everything is in the drum brake assembly as usual on a rear wheel.
Except the wheel cylinder, and maybe the self adjuster (not sure about the last part)

I'm thinking I'd make a bracket held on by the cover bolts and the side bolts.
