I don't know about all that. I am a mechanic. The only problem I'm having with parts is it takes longer to get them depending on where they come from if I have to order something.

We have usa made ujoints available.they just need to switch brands.

As far as new trucks go. Where I'm working,we just bought 2 brand new trucks. Got 1 a couple months ago.getting the 2nd this week. The second truck was delayed cuz they stopped building 2021s due to the pandemic nonsense and they can't get them to pass emissions in the states.the 2nd truck was a canceled order that we grabbed.

I'm just not seeing this supply crisis. Stores food shelves are empty cuz they are keeping them empty. Walmart food section has empty shelves but the clothes and toys and bullshit stuff seems to be kept stocked quite well.no problem buying clothes. I just came back from upstate NY.grocery stores were very well stocked. Price choppers shelves were overfilled,EVERY SHELF WAS FULL!
