Ok, i know it seems like im rambling... and i am because this is my first time doing this. Would it be easier for me to take the cab off the chassis, that way i could hook it to a chain fall and flip it which ever way i need it. Also does the cab need to be on the chassis to patch the rear cab corners? Because it not i could just take the cab off, blast it, do the patching, paint it and set it back on.
