Hey guys im trying to flash a stock tune onto a pcm as a backup, but i can not find a stock bin file frickin anywhere.

Also is there any issues i should know about. I know there is different pcms, but i though 98-2000 were all the same, but in the hours ive been looking for a bin file I have seen posts suggesting that only one particular pcm with the correct Service# could be used. I have a spare pcm i was hoping to use but its service # is 9361735 which is different from the one i saw for the 1998 regal.
