The original lagoon plastic does not fit the IPB Reproduction playfields - This one does! The item is guaranteed to fit these playfields.
Gotta love Monster Bash!
1) Make sure that the ledge inside the lagoon outline is clean. Sometimes, clearcoat and wood shavings make this a little lumpy, and the lagoon won't sit flat.
2) Don't overtighten the screws. The left hand screw hole in particular is delicate. Just make it snug. No, if you do crack it, it should not be a problem as the mounting ares is invisible hen assembled.
3) How do I tell if I have a new playfield?
On the repro playfields, the wolfman's left hand points to the top of a bulge in the lagoon. On the originals, there is a little wood showing between the black line and the lagoon. On the reproductions, there is no wood showing. If in doubt, send us a picture.
