86-89 Seville rear disc brake photos wanted

I am working on a bolt-on 1986 H-body (LeSabre and PA in this case) rear disc brake conversion project. Problem is that the rear knuckle on the H-body doesn't have mounts for calipers. I know that the '86 generation Seville shares a wheel bearing/hub with the H-body cars, but can't find any info about how the calipers are mounted. Can anybody get some photos of the rear calipers/mounts/knuckle assembly or even better a breakdown of the assembly?

I can't even find a Seville in the local junkyards, so will have to get the parts new. Unfortunately the parts stores have to order them so I can't see anything without paying for it first, which I don't want to do unless I know I can use them. I saw that the E-body cars also have rear discs, but don't know if the knuckle will bolt on to the H-body strut...

Any help is appreciated.

There some component parts pics at rockauto.com.
