custom made hitch for custom dollies

self designed hitch system for custom builds. I used true scale truck stop rails. no glue needed for assembly, all snug fitting. 3 stabilizers needed per setup. you can use standard BF1 screws from any Tamiya kit, need 4 in total. hitch is setup for pintle hitch but can be remixed to use whatever you please by removing it. NOTE assemble before installing on rails, rubber mallet should be enough to tap it together snuggly. Each main piece can be used as crossmembers.
