So that everyone has a complete set, here is an additional page that was included in the old Des Plaines kits that featured M&R sides and ALM core kits. Note that it shows the use of the "interior bulkhead" that is included on the M&R fret. As it turns out, these are actually a few mils less width than the ALM car end, fit the inside surface of the end, and give perfect spacing to fit the car side to the end, and provide a channel of sorts for epoxy or other adhesive, and provide a very strong corner joint- and also aid in supporting the floor.
