thats a load off, eh?
remember to do short welds so the frame doesn't heat up and bend on you.
one other thing to think about, once that job is done, is how you will make the trans cross member. since the old rear engine cross member is gone the frame will have a little more give to it in the area where the cab mounts are. this can cause the cab mounts to spread or narrow and that will give you a big headache and can cause cracking of the cab metal if it happens and goes unchecked
