4th gen rear brakes on a 2nd gen with 9" rear

[70PTRS]

I have a complete 4th gen LS rear brake assembly that I'm going to install on my 70 Camaro. I'm ordering a narrowed 9" from Quick Performance tomorrow and will be sending them the backing plates/dust covers to install for me on the rear. I'm also presently installing a complete DSE mini tub kit with 2" drop leaf springs so the shock mounts are totally different from the stock mounts; I won't have to use two of the same side calipers. Has anyone else done something similar and if so do you have any tips or advise for this rear brake swap? I've read where some have had to use shims behind the backing plates to center the calipers over the rotors.
I'm also planning to use the complete parking brake setup from the 4th gen including the console and parking brake lever.

how is this project coming along?

Moser #7900FM housing ends, or QP equivalent (Mike Mortensen @ QP should know what you need), axles with 2.75" offset and sealed ball bearings and you should be good to go. The only time shims are required is when you are adapting the 98-02 LS1 F-body brakes to an application with a larger axle offset, but since you're building a custom housing, you shouldn't have any issues with that. The only downside IMO is that the caliper backing plates are captured on the axles between the bearing and flange.
