A mix of Lockheed and Bendix brakes?? 1951 f3

Yup, I retract the above posting. I just put a tape measure on my 1947 Tonner with 14s, and on both my 51 and 52 with Bendix. Yours looks to be a mixture of them. What I posted originally about the features of each era still holds true. Your truck has either had a transplant or is perhaps a transition build having both configurations. Stu
