1996 Ford 460 V-8 Metric or standard

[another Todd]

I am installing gauges: Mechanical oil pressure, water temp, volts and vacuum. I would like to Tee the oil pressure and keep the original sender in the loop. Does anyone know if the sender threads are metric or standard so I can obtain the needed adapters while awaiting delivery of the gauges? OBD-1 if it matters. It seems many fasteners are metric, but not sure about senders.

They will be NPT Pipe thread, 1/4 inch.

After rereading my original post , it may be confusing. I am asking about the threads in the manifold where the oil pressure and water temp senders will go. Are the manifold threads 1/4" pipe as answered?

ShotGun429 was correct. The manifold was indeed 1/4 NPT. Thanks.
