I would imagine shipping to be around $150, but I'll check this week.
Yes, the same slipyoke from the 208 fits the 205.
The internal difference is the output shaft and bearing retainer/seal housing.
I can install a slip yoke eliminator on it for an additional $75.

edit: just re-read your post, you have a 700R4. This requires a spacer between the tranny and adapter. Do a search on here to be sure you want to go the 205 route. You might consider a 241 instead.
