C6 Slip Yoke ?

Tell me everything I need to know about C6 slip yoke.  Series sizes?  Recess the first part of the splines?  + everything else - mild 460, 56, F100. Edit - I forgot to ask about neutral safety / back up switch Lokar linkage, column shift. Prices range from $35 $50 to $XXX.

Any 31 spline yoke to suit will be fine . Depending on diff uni joints get a yoke to match , will be either 1310, 1330 or 1350 are the choices . A mild 460 any of those will do you fine .
A lokar shifter should have neutral safety as part of the shifter
