The movie was Magoo(I'm the driver) the mechanicals are : an open diff from a one ton (gmc corporate dana knock off) small block with th 350 tranny and transfercase. Steers with the skis like a B12 ,has a drive shaft brake (like a B12)and drum E brakes behind the sprockets. I was told to make this thing for the show and unlike most of the stuff we do ,made it work properly ,knowing I'd probably end up with it. I,m in Vancouver and the thing can be seen here in town if you PM me. Need to get rid of it as I moved and am now paying storage on it.
