Default 4 speed ???

I have a 428 th400 in my car now and was wondering how hard it would be to convert to a 4 speed ? Clutch pedal / linkage / pilot bearing are all problems i need to solve.
I feel the need to shift gears like i did in the sixtys
What would be a good (o.e.m.) tranny, and what should i stay away from?
car was a AT car as well was the 428. thanks Mark

I think http://www.fabcraftmetalworks.com/ has conversion kits.

Did factory 4 speeds use a z bar? (clutch in front)
or a cable (clutch in rear)
Anyone have any pics. of clutch linkage? (both stock and aftermarket)
looks like hyd. bearing is the way to go but i dont know how to run a MC to run it.
