I got all the interior details finished.  I made two matching wheels house covers that will attach to the casket floor.  Got some thick styrene strips cut...

And then made this wood guide to have something to bend them to correct to shape:

This stuff is so thick, it takes a lighter to bend it.  Then I scored the ends to snap them off at the correct length:

Here's  the finished pieces all assembled with decorative "vinyl" padding and upward directed lights:

The lights point up at these (got a  mold and cast made of this so I could have two identical carvings):

Also got the upper portion of the partition created.  The slot in the middle is for the "glass" to sit in:

Pretty much all that's left to do is mold and cast all the pieces and then primer and paint!
