Abstract:	We investigate whether 12CO(J = 1 to 0) emission lines from galaxies can be used in lieu of lambda 21cm emission in the Tully-Fisher distance indicator as a measure of disk rotation velocity. Simulations determine appropriate data rejection and correction procedures for extragalactic CO emission spectra. A CO survey of cluster galaxies out to 8500kms^{-1} provides data for comparison with recent TF work, and we find CO line widths behave identically to HI and H alpha in luminosity-linewidth analyses.
