Oil lines from tank to thermostat, part # coding

[thisisgoodnews]

Finally it's time has come to replace the all sweaty oil lines from oil tank to the thermostat. Looking at the parts scheme it's not difficult to recognize them to be #9 and #10.



However, it get's a bit confusing when looking at the parts list, where #9 has three different options:



Questions are:
1) what are the differences between 93010774312, 93010774315 and 93010774310?;
2) what do the remarks circle in red refer to?;
3) which one to get for my '85 3.2 Carrera?

More Good News,

Those look like engine numbers or code. The 930.66/68 are turbo motors so that should narrow it down to two choices. Is your engine a 930.20 or 930.21 or 930/26? I would guess...if I had to that it is the 930 107 743 15. Your local dealer should know for sure.

Best of Luck,
