With the flat flange on the rear output of the 1354 and a flat flange on the input of the divorced np205, you would just need bolts to hold the 2 flanges together, provided you made them have the same bolt pattern, no intermediate shaft, no ujoints, no extras. Just cut off the front output portion of the 1354 and weld in a filler plate to seal it back up. Drive shafts will now need to be longer up front and shorter out back, and some sort of shift linkage will need to be made to shift the second tcase. Not to mention you can twin stick the 205 and modify it for front digs, hell yeah!!
Gwaii, what would you do to mate a married np205 to the back of a doublered 1354? The adapter is easy, but the spud/intermediate shaft is the kicker! All ford drop 205's are 31 spline input, and the 1354 output is ?? Wouldn't mind hearing your take on this.
My set-up is changing here shortly, wanted it to be v8/c4/1354/1354, but since no one makes the shaft or adapter for the 1350/1354 doublers anymore, I'm starting to think outside the box for possibilities. I would rather not go with a c6/205 as that will add length and no reduction and a worse low range gear too boot. np203/205 doublers are cool, but attach that to a c6 and your length is way out there for my wheelbase. I'm definitely going auto with the v8. BII's are short wheelbase to begin with so adding 4 feet of drivetrain underneath wont happen with mine. I have added 4" front wheelbase and will be adding 4" rear wheelbase over the winter.
jamie4ltr, couldn't you put a BII tank in the back of your rig where the spare tire under the box rides?? They hold a lot of fuel, and are likely as big as your stock tank along the frame. They're not overly expensive new and will use your existing sending unit, tho you may need to lengthen the wiring harness and fuel lines, but that's not overly difficult. You could always hit the JY and grab a tank and skid plate from a 86-newer BII at the same time. Just an idea.
