I have the 6" superlift, Back when i still had the 350 I drove mine with no front shaft to the nearest muffler shop, had them cut the driver side crossover and bend a new one that hugs the bell housing, then welded an o2 bung to it, costed $60 and they had it done in an hour, the guy even let me throw my driveshaft back on while it was on his lift......ive also seen people extend it around the drive shaft, both work just as good
