There are 2 standard hitches, 2 drop hitches, and 4 tow rings. These are injection molded out of GREY ABS plastic (same as legos) and can be painted, and glued. 
 
In the last photo they are holding up two set up blocks at 1lbs each. After lifting two pounds, there was no sign of stressing.
 
These Hitches are compatible with MOST 1:24 and 1:25 scale OEM vehicles. 
 
*These hitches were previously sold as our 1/64 scale as oversized hitches. The photo is shown on a 1/64 scale truck, and can be used for that scale to haul larger farm equipment.
