Who's ramp is this  Micky
the original WMS
the Pinball Inc ramp 
or the one from TPF

as i'd be interested to chronical which fix goes with whos ramp

Hmm, I got it off Wayno in '07 so not sure who made those repros.
I've tried moving the plunger around (by loosening the screws on the mounting plate) but it never hits the ball dead on.
I've also read that if the PF isn't levelled correctly, it can 'twist' and cause problems that side.
Tho I think the majority of FH's have this problem
