Staggered boss 338's on a bagged 86

[86beater]

Wondering if i could fit a set of boss 338 wheels in 18x8/18x9.5 for my truck? Everything needed for it to lay frame is here but i havent started it yet. Big question is mainly what tire sizes to go with. The offsets are +2/-4 front and rear. Dont mind a square setup but id rather go staggered. Any info if theyll work and tire sizes please?

Well no reply so i only ordered the 8" wides...no go on a 9.5 rear cuz with the 8 ill still hafta cut or roll rear fenderwell lips. Wonderin tho on front now cuz the 8's r too wide but since ride height will b like 3" n the amount of camber ill b at if i could stuff the 8 on front with trimming the fenders. If not im stuck with a 17x7 front i guess
