I suspect it is 1 or 2, but I have my new truck sitting in Texas with a burnt out motor in the DS. It, of course, is all the way forward. A drive in a seat like that when you are my size (6'4", 240lbs) is not something I can entertain. I need to swap it out in advance and/or fly in with the part and do the work before I leave. Anyone know how long this would take and/or have a source for a CHEAP replacement?
