I'm installing a t176 soon and will need new driveshafts. My rear pinion is
pointing slightly under the t-case output at the moment, but might change
with the new tranny. Either way, I'm going to get a tom woods ds made.

Tom Woods recommended that I get the double cardan and point the pinion on
the rear end just below the transfer case ( I have a HEFTY traction bar that
keeps the rear from wrapping under acceleration). I will have to change the
output yoke on the dana 300. They sell the required yoke for $60. The booted
driveshaft was $329 and Until Dec 31st they have a 10% off deal going. They
custom made the drive shaft with 1310 u joints at the dana 300 end and 1350
u joints at the rear pinion so I would not need the "bastard" u joint
anymore. Now I just need the 176 shifter fixed and the dana 300s seals
replaced and I can put it all together.
