I recently acquired a NP205 (thanks Bryan) with a rear slip joint output (circa 1980 model) that I'm changing over to a fixed yoke. Went hunting for a new rear output shaft and found out from several different sources that they are no longer available (new). Old ones from tired cases are still out there but they are few and far in between. I did acquire the last new shaft that 4xHeaven had in stock (I think this was about the 9th place I called)(sticker shock $250). Some info that I did pick up is that all 205 rear output shafts are interchangeable along with most of the internals. (Ph**d, left drop, uses a 32 spline front and rear output, which differs from GM and Dodge versions, right drop) They do recommend that you change the roller bearings out when you change the shaft. There are two different front output shafts on right drop 205's (10 spline Spicer style and 30 spline Saginaw style) . Input shafts, well I think we all know there is a variety of them. If your looking for a 205 (pre "85) that needs a TH400 input, (SM465 and TH350 types) the input bearing hole will have to be milled out to accept the larger bearing required for the 400 shaft. Just thought I would pass this along for those who have a NP205 or those who are looking.
