Bump again since this remains unanswered.
I spoke with Steve at Pinball Resource about replacing the compression springs on my EBC flippers, and he told me that the older KT-BFLIP-03 kit works for EBC if I wanted to do a full rebuild. The geometry of the link is a little bit different (rectangle vs "A" shape), but it looks to me like someone prior to me installed the PBR plunger/link assembly and it works fine in my EBC after I replaced the compression springs. The new springs are a little bit heavier than what was on my machine when I bought it and would not always keep the flippers all the way down before replacement.
It seems like the link is at least close enough to the same as OEM that any difference could be accommodated by adjusting the flippers.
The difference in the shape of the link might reduce the ability of your existing return spring to work, so I would get Steve's springs at the same time as the plunger/link assy. The springs were less than a buck each, Item No. WIL-10-135.
