Anyone running this system on your small block? What else will I have to change or buy to run this on my 69?

Have you checked out gmpartsdirect.com, they have a genuine gm serp setup that comes with all the necessary parts and bolts.

careful on the march system.
it is on my 70 w/zz4 motor.
do a search on the march systems and you will find a lot of grief.
previous owner had the wrong motor frame mounts and when i put the correct mounts in, the power steering pulley hit the steering gear box.
my original steering pulley was about 6" diameter.
i replaced it with a 4 1/2" pulley from a place in Pa.
can't remember their name right now.
i'll have to find it and post later.
