well i decided to add on to many of my current project for the 40, a couple of weeks ago i decided to build my own tire carrier after looking a some threads on mud. i built the carrier to hold either a 38" or a 40" tire. the lower pannel and the swing away bar is 2 1/2 1/4 thick and the suport bars for the tire are 2 by 1/4 thickness, hope yall like and i will post more pics up when completed.
