The bolt hole that has to be drilled is a 10mm x 1.5. Start with a small drill bit. I used a 1/8th for the pilot hole, then swap in a larger bit (3/8th). Then tap the hole. Run the tap down and back several times. Use plenty of cutting oil the whole time.
Set the depth of the drill bit around 1.5". This will give the tap enough room to cut without bottoming out, enough room for the bolt.
It's easy. Nothing to it.

The oil pressure sending unit has to be swapped over. The truck uses a 3 wire, the f-body a 1 wire. I've always thought that the 1 wire was a stupid design. It's plastic, super tall, and after several years in an engine bay gets brittle. I've broken 3 of them. I've often wished someone would make a kit to swap in a metal one off a Ford. If I remember correctly, the 2004 GTO also has a 3 wire oil pressure sending unit.
