I have thought that too but I haven't been able to find any reasonable priced plating company from Finland and shipping stuff back and forth will "eat" the benefit. Now I'm trying to find suitable metalworker that could fix originals, there is standard "bolt-through-lockdown-bar" fix so it needs some welding. Siderails has common backbox's edge damage but it may be restorable. Machine itself is in excellent condition, almost no wear in playfield (very minor at the electric chair scoop=cliffy installed) and cabinet is 9+ so those little things are quite annoying.
BTW: machine is for sale... (new NOS ramp, thing hand, plaque in place(no cert), etc.
