Where do you buy your aftermarket parts?

[Grumpy Bear]

For items like the tonneau cover I use a local Line-X/Truck Gear shop. For custom hard parts I go to the manufacture. If they don't sell direct they have a list of reputable dealers. PM parts the dealer or O'Reilly, AMSOIL. For repairs of existing parts I use my local wrench. Things like wheel straightening he has the resources and motivation to get it done. Some specialty parts are sourced through a limited number of select dealers or even just one. A few items, common items Amazon or Ebay.
