Should I put bumper plugs on system-7 flippers?

Hi All,

Doing a flipper rebuild on a Black Knight. Should I put bumper plugs on the flipper assemblies? They don't have them at the moment. If so, are these the right ones?

Also, can anyone confim which way up the coils should go. Right now the tabs are at the coil-stop end but I think I read somewhere that they should be the other way around. Correct?

Thanks, SV.

Yeah any that looks like tw right one.  The lugs should go away from the coil stop less impact from the flippers

Thanks Daniel,

So you put the bumper plugs in a system-7 game? Did it make it better or should I not bother? I'm pretty sure they didn't have them from the factory.
