What is this?
The easiest way for the pickup is to put it on, make sure it is about 1/4-3/8 inch from the bottom of the Pan, mark it and then have it welded. Just put a couple of little tacs in it, so it stays on and doesn't move. I did that to mine, it's a little insurance that can save your motor.
