Grady, from your pictures it certainly appears that passenger side front mount seems to be twisted, but that could be a frame issue and not the cast bracket itself. Considering this also appears to affect the running board mount also attached to the frame in the same area, you may need to do some measuring/checking of the frame for bends or twists. Below are snaps from a 1948-51 Shop Manual and 1947-54 FAM with frame measuring points and dimensions that you could use to check your frame. To my knowledge, there isn't really any way to straighten a bent "cast/forged" spring mount but others may have more info to answer that question. Best of luck!
