a little help please fellas...

yeah im wanting to build a back half on the model im doing and wanted to know what everyone uses to make the frame out of ..also i have seen people make something that looks like airbags

use small  o-rings glues together or airbags and for the backhalfs i build i cut the rails out of a sheet of plastic

after thinking about it i thought plastic hangers ...could even use the bend for notch or tube work also could heat and bend it

rpphobby.com has the toyota models .... that is where i order all my models ..... i have built 3 standard cabs and a crew cab
