White Motor bought Diamond T in 1958 or 59.. This ended the DT / IH relationship which had started during or just after WW 2.. It is believed that the IH Compfovision cab was a joint effert of both design engineering departments. I doubt if White used any IH parts after that?? BUT both may have used the same suppliers for components like engines, trannys, and axles??

GeorgiaAndAdam As I said I know nothing about Diamond T's but from what others are saying here, it looks like your Red Diamond motor, the front axle, maybe the cab, etc. are as the truck was built. I would not be in a hurry to change anything. Just clean it up, do what you planned for it and enjoy it. Don't take any notice of what purists, maybe they are what are called "rivet counters" on this forum, most of them do not have a truck similar to yours and probably never will.
I have my shoulder to the wheel,
my nose to the grindstone,
I've put my best foot forward,
I've put my back into it,
I'm gritting my teeth,
Now I find I can't do any work in this position!
