Thanks Dann. Haven't had much bench time lately but did get the tin's hinge repaired. You can see the broken hinge (painted black) in the center of this photo.
After reattaching it I added a piece of angle to reinforce it.
So I checked the Moebius '65 against the AMT '64 and the wheel base is nearly identical. It's not a drop in fit for the Moebius chassis but doesn't appear it would take much work.
