The flipper travel is problem for older flippers too, in case you have to buy a new bracket for flippers (C-16103-R/L) - they don't allow as much travel as original parts B-13104-L and B-13104-R and then one has to bend the bracket in order to get greater travel.
Have a look e.g. here: https://pinside.com/pinball/forum/topic/proper-replacement-part-for-wpc95-flipper-base-assembly#post-4222354
Somebody should start manufacturing proper flipper brackets for WPC-95 machines as well!
