4spd parts

I am in the process of converting my 68 340/auto GTS over to a stick and I am looking for a few pieces.I know that I can buy stuff new but would prefer to find good used parts instead.
4spd carpet in black,worn and faded is fine.
4spd hump
z-bar frame bracket
overdrive trans front bearing retainer
and if anyone has a new z-bar service kit and wants to part ways with it I am also interested?
I am in CT.06018
Thanks Doug
I will be posting more as I progress with this project.
