Yeah - the search on RCU isn't the best and you have to try a few variations to find everything.

The LT-40 is a downsized variant of an older SIG kit called the "Kadet" - in fact the full name of the LT is "Kadet LT-40". There is a website dedicated to kit-bashes and mods of the Kadet and the LT-40 at [link=http://www.angelfire.com/indie/aerostuff/kadets.htm]http://www.angelfire.com/indie/aerostuff/kadets.htm[/link] that shows clearly just how forgiving this airframe is to modification.
