340 Pully
Curious when the 340 pattern changed. The 318 went to the symetrical pattern in 72, so either
a) the 340 kept the offset hole through 73
b) the OP's "72" 318 is really a 71 and earlier
c) that particular 318 was built with leftover 71 parts
d) somebody changed dampers
Just curious what the deal is.
