my neighbor did a self conversion of a PW excel on a 1999 ford to a 4x4 in his driveway.
he had a sprtsmobile which burned down...he saved the chassis...found a '99 excel and started swapping parts.
he had to find a way to relocate the fuel and the waste tanks, spare hangs off the door, I don't think he was able to keep the genny.
just walking the dog by I'd guess it took him 6 weeks of week ends in the driveway.
he did it for trips to Baja, he says it's great down there on teh dirt roads, not so much good for hey speeds
