Widest rear wheels with 7" Drop w/inboard 4 link Coil over

[Custom.Chevy]

Running a 7 (ish) inch drop at the most. Don't truly know anymore due to the custom suspension I'm building. I'm in progress of building a 4 link coil over using ride tech HQ coils overs mounted on the inside of the frame along with the 4 link. I was wondering if anybody else has a similar inboard suspension set up with super wide rear wheel/tire set up.

Also thinking about narrowing my rear axle down the road getting custom axles built, re-gearing, and doing c clip eliminators, along with a disk conversion. Does anyone know if C-clip eliminators widen the rear wheel track in any way?

These questions may have been asked before but i have a hard time finding these answers specifically regarding square bodies (with exception to the c clips part)

picture for attention.... my truck before i tore the bed off , cut the frame for notch , and started my rear suspension upgrades.
