TA Vento rings for 135 - chain drop pin location?

[zank]

Question for the group that I have not been able to get an answer on from other sources.

Where is the chain drop pin located on outer TA rings for 135 bcd Campagnolo cranks? Is it positioned for 5-arm spiders, i.e. 03 and earlier Chorus and 06 and earlier Centaur, or for 4-arm spiders, i.e. Record, 04-06 Chorus and all Ultra-Torque cranks?

Small detail, but I don't want to jam a chain down into the bowels of a Chorus carbon Ultra-Torque crank if I can help it. Thanks!
