Does anyone know the differences between pre- and post-R5507 window regulators for Avanti power windows? Are they interchangeable? How can one tell the difference between the two?
I have two NOS regulators but they're not stamped with part numbers and the buyer needs to know if these are correct for his car.
Thanks to all in advance.
