i have plans to do this next spring and am getting all of the parts lined up. i am trying to figure out if i need the extra crossmember, ie cab on k5 frame. all of the sites i have seen so far on the net have no info concerning this particular aspect of the swap for a burb frame. i searched and had way too many hits to go through all of them. i know that someone here has come across this. /forums/images/graemlins/1zhelp.gif thanks.
