"Cliff do you have a photo of the stock pickup?"
I did Tom but lost them when my last hardrive crashed. To effectively retain the stock pick-up all you need is a small hardened machine screw, I use 8-32 pan head.
Correctly install and "locate" the pick-up on the pump.
Remove the pump and gently clamp it up in soft jawed vise.
Drill the pump just inside where the pick-up goes into it..
Tap the hole for 8-32.
Remove the pump cover and gears. (Good time here to clean-up the associated parts, remove any casting flash, smooth/blend oil passages if/as needed, etc)
Blow out any filings and metal chips left over from the drilling/tapping/clean-up operation.
Re-install the pump cover and torque the fasteners (I also use red Loctite on them).
Install the hardened screw and retain with red Loctite.
The entire operation typically takes about 10-15 minutes and the pick-up will NEVER move for any reason......Cliff
