> I hope I never lose the lug nuts
I try to keep 2-3 extra (especially a left hand thread) in the glove box. That way if the lug gets messed up taking it off or you have to re thread a stud with a nut you can. Or double them up on a stripped lug.
PLUS, if you lose a wheel, if you have 2-3 nuts and can rob one from each remaining wheel you can usually limp home.

yup, ihc too. left is always on the left unless someone put that hub on the wrong side. or got a left/right junkyard replacement, etc. in 40+ years of wrenching i've never figured out why. i've heard the self-tightening story. never sounded credible. i think they did it as a mechanic's intelligence test, do you notice the L or slash before you snap it off with the impact?

I've worked on a '59 f350 and a '60 f350 and they both had reverse threads on the drivers side. First time I had ever heard of such a thing and belive me I broke quit a few studs before realizing what was going on.

I may be wrong, but I believe my fathers old 84 f250 diesel had left hand nuts on the one side (front and rear). It was the first set of tires I ever changed (I couldn't have been 10 at the time), so it REALLY threw me for a loop.

GM used them on a number of models in the 50"s and 60"s. Had a 54 Buick with them. Also ran into a LH thread on a 300-6 fan nut. And it was on tight!

Here's my stupid story---bought a 50' International Harvester pick-up back in the 70's. Wanted a spare tire--found a pick-up just like mine in an old-country junk yard. Studs and bolts were all rusted up, so not knowing any better spent 5-6 hours with hammer and chisels busting all the nuts off. Later had to change a tire at home, and finally figured it out.
