Hello all,
I've invested in a set of new ATD springs (PR22A/D, Lucas 498157/S). They're claimed to be NOS Lucas, but arrived without the original packaging - so I have some concern as to whether they're correct. These are identical to each other; I believe some designs use two different springs in a set, providing a more complex advance curve.
Does anyone know if these springs should be identical, or different from each other?
Thanks,
