The VS4-10 Mud Truck Conversion uses laser cut CNC parts from SendCutSend.com that are available here: https://marketplace.sendcutsend.com/p/CM94M097/vs4-10-mud-truck-conversion

After you have purchased the parts from Send Cut Send, the 3d print files available here are made to add a little bit of extra bracing when using H10 Axles and Link sets as shown in the video which you can watch below.
