It's like...the easiest gearbox in the whole world. Literally. In fact, it's not criticism, but he didn't disassembled it the "right" way. Instead of taking those 2 bolts out, of the reverse gear, he could have unscrewed the upper bearing cover, and half case lifts up super easy. That way the 2 shafts remain in the front case and then you can take out the 2 bolts... much more comfortable. But great job anyways
