Hi all - in my search to slowly piece together the bits for my 930 brake upgrade for my 74, I've come across two different turbo boosters. The part number up to 84 is "930.355.027.00" and post 84 is "930.355.027.02" (until the 964 that is). Does anyone know the difference between these, if any? Or was it just a subtle part # revision? Thanks
