I used 2 sizes of evergreen strip, as it got me much closer to a snug fit around the chassis stub. The .080 is used in between the 2 100x100. Just measure the tabs on the chassis to get the correct width of the opening needed. The original poster used the 100x100 for everything which is ok, but it left the fit sort of loose, and I choose to file to a fit I would be comfortable with.
this after the parts were removed from the glued piece. I used a Exacto miter saw for this.
Notice the chassis tabs are visible through the mount, they sit against the body and center the chassis. When gluing the tabs into the body I just push the 2 parts out against the body then glue in place.
Filing the parts for a nice fit, also filed a tapered edge on the side to help when snapping the body in.
Used some scrap metal to set my height then glued along the bottom edge.
After the bottom dried, I glued along the top edge and the sides.
all glued in solid
snapped back in
and complete
