El Cheepo conversion of Scientific Toys cars from Single axle to double axle bogie Start with your typical very inexpensive type car:
Remove the bogie, cut off the side frame:
If you have New Bright trucks, its a straight conversion, no mods needed
If you have other trucks a shim will be necessary, this is two .40 styrene pieces:
make sure the shim is wide enought to allow the level bumps on the chassis to rest on the shim otherwise the car will wobble. FInal product, I used a brass retainer with the screw to hold the truck. I have link and pins so thats what shown. If you have couplers on your trucks they go right along with the truck OK.
