The printed circuit has an ID number printed on it. These printed circuits are specific for certain years.

1973/79: Originally there were SEVEN different ones!

If the ID number is one of these four, it will not work on some 1975's (depends on the '75's serial number), 1976/79's.

D3TF-10C956-AA / D3TF-10C956-CA / D5TF-10C956-AA / D5TF-10C956-CA.

Post what the ID number is.

I'd have to look in the parts catalog to be sure, but I think 1976 was the last year a 100 MPH speedo was available.

my buddy has a 77 F150 with a 100mph speedo not sure if some one put it in there or it was O.E. his dad was the orginal owner of his truck but he said that his cluster back had been replaced once before.

I was gonna give him my warning light panel in exchange for his gauge panel out of his econoline 150
