ok,on the procedure i'll start with some history.there's lot's of these f350 crews littering the logging roads of this island since logging went belly up a bit ago.i got two(a 94 and a 96-regi on the 94)that had been sitting for about 5 years in trade for some paint work on a logging truck hood.they were both pretty rough,but the 94 was rust free,and so a good base.stripped her down to bare bones,did the body and paint(with a little tinkering it ran fine)and ran it as a normal crew for a while....but i had this idea,an extra truck,and took some measurements to see if it was feasible.the key is that the back edge of the front doors and the back edge of the back doors have the same profile,so they can be stacked.the trick was to create an opening identical to the back door opening in the middle which was done by cutting the cab on the donor truck in the middle of the front door and removing the rear cab.the main truck was cut in the middle of the rear door,so that when they were put together(after very carefull measuring and on the already stretched frame)i had my third opening.the rear floor pan on the crew is the same as the front,so these lined up perfectly.the center fill panels are just rear doors with the windows filled in,held by the latches and hinges-but dont open.they are however very easilly removed for better access to service the stereo stuff or middle seats.ford used the same rear shaft as the standard cab but with a 3' second section for the crew-i just added another section from the donor to make a 3 piece drive shaft-lined her up good and it does 100 mph on the highway vibration free(you didn't hear that from me
)the roof is still a bit rough at the seam,but it's being cut out anr replaced with the roof from an explorer soon.it's just the right size to replace the courigated middle section on the 350,and it has the power sunroof.
