MUTT MAGS?
Q: I was told that some early M151s had magnesium or aluminum wheels. Is this true? And would they be correct for my 1967?

In an attempt to lighten MUTTs for air transport, the military ordered “mag” wheels in the late 1950s and tried them for several years. While they were lighter than the steel wheels, they were also prone to corrosion and cracking, so the military switched back to steel wheels - with more holes - around the mid-1960s. While your `67 wouldn’t have come from the factory with mags, it’s possible that “boneyard” mags could have been installed—though more likely only one as a spare wheel—so on this basis you could still call them “correct” for your vehicle.
EASY PULL-OUT
Q: I have a 1943 MB all stock. My problem is the oil filler tube is loose in the engine block Oil leaks out and the tube comes out sometimes when I check the oil. After reading your advice about silicone seal getting into places it shouldn’t be I don’t want to use it to seal the tube. It seems like a shade tree fix anyway. JB Weld might work? What do you think?—Bill Kenichi
A: Silicone seal would probably work, and if applied carefully, shouldn’t get into the crankcase. JB Weld might be a too permanent fix, because you may need to remove the tube someday. And of course, neither would be a “correct” fix. Why not use your
