Has anyone on here built the M-42. Ran into a wierd fit problem on the bottom of the tub and ended up having to cut part of it out to make the bottom plate fit. Also, anyone used the Verlinden resin drivers compartment add on? There is a shelf of some sort that mounts somewhere to the top of the compartment in the center. I am assuming I need to scratch build a support? It touches nothing to glue it to.
