No luck on Ramchargers yet, I hit one of the big (and cheap$$) yards yesterday on my way home but struck out on everything.
On the 208, I will know on tuesday for sure, but I think I may be able to offer it as a complete 32spline unit. I traded a buddy a spare 27 spline 208 I had and never picked up the the 32 spline unit he swapped out (he went from a 400 to a 700 trans). As long as he still has it, if your interested I can put that one together with my back half and it would be a bolt in swap for you.
