Mopar thrust bearing failure

[devo340]

I keep killing the thrust bearing in my 360 Stocker after 10 passes.
Last time, had the thrust repaired on the crank, freshen the convertor, changed to another 904 trans, did away with the quik disconnects on the trans cooling lines.
After the thrust repair, I had .002 endplay.
The time before, had .010 endplay.
All the bearing look great.
Anyone else have this problem?
