68 camaro widebody

Does anyone know how much it would cost to get the rear quarters replaced on this camaro? And does anyone know if the wide body kit is possibly removable to go back to stock rear quarters. Also, would it look okay if I just got wider tires and rims if it cost too much to replace rear quarters to factory?

its about 2500 bucks a side in labor for the quarters plus quarters, I have seen some shops just slap them on for 1200 bucks a side with really bad gaps and seams

Somebody somewhere is going to love that Camaro for the big booty it has.
