It looks as if, unless the hard parts are specific to the 425, the planetaries will, since they are helix cut, apply their side load to the opposite end of the pl;anetary, will they not? I defer to the Guru, but if this is the situation, I can see where there might be cause for concern, not only in strady deceleration load, but particularly from shock loading if one simply stuffs it in S at 40 per or so.

That was what i was trying to say, and it was discussed here a while back. KenH has put that theory to sleep with his confirmation that the 425 does have its own unique gear set, cut correctly to handle the reverse rotation.
