Quoted from cerberusdog:I know this is an old thread and the link is dead but any leads on getting these? My Apollo13 is missing them and I like the look of these over the plain white ones.
There are some custom Apollo 13 apron cards here - http://www.pinballrebel.com/game/pins/instruction/
There are two available, grab the "Apollo 13 Custom" as the other is just the basic white one.
I like the cards above posted by zachster better, but the ones at the link are a step up from the generic type.
If you want to see what they are like printed, I used a set on an Apollo 13 I worked on recently - http://www.enteryourinitials.com/2018/05/07/apollo-13-repair-service-log-1/
