Score Wheel Guides
GOTTLIEB SWEET HEARTS
These EM score reel guides disintegrate over time, I have reproduced these using a 3D printer, These fit in 60's Gottlieb games with the "Rat Trap" score reels. It is possible they can fit on other games.
I drilled out the original rivets and secured the new guides with M3 x 10mm Fine Threaded bolts and nuts.
