It’s defence, ... it’s everything.
Late model vehicle parts with all sorts of stockout and backorders, even for high volume parts.
And the vintage stuff, you can get the old flat tappet lifters and cams, but they are now unreliable junk with multiple failure modes due to manufacturing and material problems, as well as the oils.
Supply chain issues for advanced parts are an absolute catastrophe right not. Zeepers have no idea.
Sure, I can order some crappy kitchen blender from Amazon and it'll be here tomorrow.
But circuit boards and servos for advanced munitions? 7.62 NATO rounds? Civilians have no idea of the backlogs we're dealing with.
