Do the 67-72 core supports work for the 66 F100?

They look pretty close to my eyes.

 

Not the same, 1967/72 is a totally different truck that shares no sheet metal with 1961/66's.

Does this 1964/66 core support resemble 1967/70 or 1970/72 core supports? No, it doesn't and there are TWO different 1966 F100 core supports!

1966 F100/250 2WD uses a different core support than 1966 F100 4WD.

 

Just get a repro one and fix it. https://www.ford-trucks.com/forums/1...or-66-use.html

 

Bill what core support would a 66 f250 4x4 use? the same as the 66 f100 4x4?
