Here is the AA adapter kit with the shifter bracket included:

And FYI...when using this bracket, it kept the length of my trans-tcase for the NV4500/205 the exact same length as my previous TH400/205 length. Which meant there were no driveshaft mods I needed to do (and as far as I understand, your later 465 should be the exact same length as the 4500 too)
