ufff...
hate it when they do that
our company does this too... always trying to get TVH parts
the only way i can get OEM is to specifically request it when placing the order.

i do alot of work on aerial lifts and it is imperative to use OEM oarts on those machines, i can't seem to get this through thier heads because they are always trying to give me aftermarket junk. I have to put OEM part only every time i order parts usually.

i've had too many aftermarket part failures for my liking so i just tell them OEM.
