LO23 Clone, Shifter Lockout Install

I am following this with interest. Is the shifter and handle you chose the one that came originally on the L023 back in 68? If so, where did you obtain it/cost? Thanks in advance.
I bought it from Passon Performance a couple of yrs ago. Just now ready to install. Price was pretty speedy but I bought the tranny clutch and QT scatter shield all at the same time. I'm thinking the shifter was like $500. It is supposed to be a correct rebuild????
