I have ordered from LMC,Filling Station, ChevyDuty,The Truck Shop and several others. I think it is what you order and who takes your order in many cases. Ordered Turn signial switch from The Truck Shop wrong part was shipped, called and they took care of the problem. I got to keep the wrong part plus they overnight shipped the correct one. I shop for fit, quality, and price. Vast diffrences. If I could by all NOS parts I would but that is just not possible. I buy repo's insted of used to save time with my restoration I don't want to buy a part and have to spend more time restoring it before I can continue. If you have questions about vendors ask here the opinions will be mixed and many then you decide for your self. Just my .02
