Tires and alignment complete. I went with Hercules TerraTrac CH4. A nice highway tire that is very affordable. The PO had 245/75/R16, but I switched over to LT235/85/R16. A taller and thinner tire should help with MPG and it greatly reduces steering effort. Running 40psi in all 4 tires for now. I can switch that to 60psi front, 80psi rear if it ever gets a heavy load.

As for alignment specs, I was surprised to find that the Hunter alignment machine at work had factory specs for a 66 GMC 4x2. Modest positive camber, about 2.5* caster, and a pretty insane amount of positive toe. It wanted 0.18*, but I left it at 0.15*. Just a word of advice: if you bring your truck somewhere for an alignment, make sure to give the tech coffee and donuts. Camber shims are no fun to mess with. The tech will be grateful and will ensure that your alignment is dead on, not just "good enough". Talking from experience here. Lol.

And of course, my posts would no be mine if they didn't end with a new problem. My blinker fuse keeps blowing at random. I haven't found any way to get it to blow reliably; I don't know what's causing it. One minute they work, but the next time I go to turn them on I suddenly have nothing. For now I'm going to do a "fix" by installing a breaker instead of a fuse. That way I can get blinkers back when I'm on the road. Also saves me money. I've already put 3 fuses in it this week.
