trying to find oil pump relief spring please assist

I use a small drill to put a hole in the plug, and screw a self-tapping into it,, and pull it out.. I can't remember if the mopar pump plug has to seal, I've done this mod to all breeds, so I would replace the plug with new,, or weld/braze up the hole if nec.. clean everything of course..

I've never put a plug in without having the "spacer" in there,, and never had any trouble re-installing ...

PS.. after doing all this work to the pump,, make sure it turns before you install it .. sometimes the idler gear is installed upside down,, and seizes the pump.. and that's not discovered till fire up, and no oil press..

PPS - While this may not be Recommended Service Proceedure now,, it was wayyy back then.. cheers

hope it helps
