I just p/u a b4.2 roller & wondering is any parts like arms, shock towers are interchangeable to b4.1?
the short answer is kinda. The arms are the same, but the towers are different. That being said, AE it not making the old style towers anymore and they are doing a rolling update on them. The old tower will fit, but might require some spacing and dremeling for the big bore shock clearance.
