Oil pump install question.

Ok so the motor is out of the car and while I’m at it I’m going to change the oil pump. Can someone tell me the dos and don’ts of threading the oil pickup into the new pump? The book I have only address the height and alignment to the pan but says nothing about connecting the pickup to the pump. Do you use any type of thread locker? What are the common mistakes people make? Also would it be prudent to replace the front transmission seal on my 727 before putting the motor back in? Thanks all will check back after work today.



I tape two nickles to the bottom of the pick-up, then test fit the pan so the nickles hit the pan when placed on the block with no gasket to set the pick up height, then remove the nickles and install the pan...
