What is the size of the socket that I will need to take the oil pressure sender unit out. I am putting in a autometer gauge. Not sure if I have a size that fits. Thanks.

It's a special GM oil sender socket available at most parts stores for $6-$8.

Otherwise you may be able to get it with vise grips or channel lock pliers.
