Hey everyone, this is a picture of a front spring on my '76 F250 4x4. I know they are not original for that year as they are 3". I've google searched and still cant definitively determine what spring it is. I did however I.D. the rear springs to be D2TA-5560MB (1977-1/2).

I'm trying to determine what it is so I can replace the bushings.

Thank you in advance.

 

Those are original springs for sure. Those are the 1550lb springs.
