Hi Guys,
I've been offered an Underdrive pulley but the Guy doesn't know what year of car it came from.
Apparently there was a big change around May/June '08 and it would appear that the pulleys aren't inderchangeable.
My car is a 57 (UK so Sept' '07 to Feb' '08) so should fall sqaurely into the early category.
What physical differences should I be looking for in the early and later pulleys to establish if this will fit?
Thanks.
Ben
