Excatly. Thats what dimarzio CS told me and they fit just right. However, it's not real critical, you can use 2 F spaced. Theres a particular ebay seller however that seems to specialize in selling dimarzio 36th set with F bridge and R neck together.The ideal setup for putting Dimarzios in trem equipped PRS', is Std space neck, F space bridge, then both should line up perfectly.
That said, I wouldnt lose much sleep over not getting that setup as its close either way.
