READ ENTIRE DESCRIPTION! - NEW DESIGN! - Lionel Piggyback Trailer Stand Kit for MPC/Modern Era - With Single or Tandem Axle Trailer. This is a new redesigned trailer stand kit that will hold single and tandem axle trailers on MPC - Modern Era Lionel piggyback cars. NO CAR IS INCLUDED! KIT ONLY! This kit bolts on by a noninvasive method that utilizes an existing hole in the flat car and round counter bore over the truck bolster rivet. No modifications to the car are needed. The kit can be easily removed if needed with no trace it was ever attached. This kit will keep trailers in place and sitting level as the train is operated on your layout. You will receive two stands with mounting hardware to mount to your car. This kit will not work on post war 6430 style cars. I have a kit for postwar 6430 style piggy back cars in a separate listing. I charge a flat rate of $5.00 for shipping. I will make shipping cost adjustments if you order multiple kits. I accept returns for a reasonable circumstance. Please review the description and if in doubt ask questions prior to buying.
