HO LA Metro P3010 Floor Kit

This kit is designed to fit into the P3010 body shells sold separately in the West Coast Traction Supply store. This kit includes the A and B floors, a set of sideframes for a Bowser drive, and a pair of semi-functional couplers.
This is designed to accept a Bowser three-truck traction drive kit, item number 125158 (no flywheel) or 125158F (with flywheel), which is available from CustomTraxx at www.customtraxx.com.
You'll need a handful of 2-56 x 1/2" screws to assemble this, plus all the screws provided in the truck kit.
When you install the middle truck to the articulation unit, tighten the shouldered screw down until it locks the truck rigidly to the center section, but do not overtighten or you'll strip the threads. The articulation unit is meant to be rigid with the truck as it is on the real car. You could even put a drop of glue between them to lock them together if desired. 
Gently sand the rough printing texture from the articulation end pivot ring surfaces of the A and B floor.  
Install the floors into the end units after the trucks are added and wired, then hook the A (motor) end floor over the post in the articulation section floor, then hook the ring of the B unit over that and your car is ready to go.
