My "prom" book is dated, and my friend at the GM store ain't there,
anyway, I saw 30, yes 30 proms for the 92 3.1L T code engine 
for stalling problems.........Then there are probably 20 other numbers
for proms, I have no idea which end is up on that.
  I do have one unmarked bin for that application.
  You might contact Peter, and ask what exactly he did on his pintle.
Cheers
