70 duster tires & wheel size?

[fivefivem]

am installing a hotchkis tvs system on my 1970 duster. no body mods. need some help from someone to tell me what size wheels & tires i can run without body mods? also what backspacing? any help greatly appreciated. running 8-3/4 rear with disc brakes if it matters. thanks in advance. mike

we used a percy wheel and tire simulator that bolts on the hub , that way you know what will fit , you never truly know if the rear has been switched,unless you really know the cars history.
