[5851a]

I once converted a 52 F series and used the gauges from mid/late 70's P series trucks. They looked the same and bolted right in used the IVR and they worked. I left the gas tank sender up to the owner as he was using a large tank on the frame of the F-6. The older bimetallic IVR's sometimes had a little "Choke" added on them that I assumed was for radio interference. Good luck with your project. I didn't use the P series amp gauge because the original worked fine.
