part number needed - 2L needles

["John F Sandhoff" <sandhoff@csus.edu>]

The parts fiche lists three different part numbers for the SU needles
for a 2L. Does anyone know what the best part would be for a
desmogged '69 engine? (No air injector, recurved distributor; so
I suspect I want the pre-smog, leaner needle of 67.5 - but which one
is that??)

Finding the right part number will save me from playing 'mix 'n match'
with my box of spare parts :-)
